The economizer is a device designed to improve both cooling capacity and efficiency of the system, by providing an additional sub-cooling, achieved with the addition of an intermediate plate heat exchanger, expansion valve and the cross flow refrigerant circuits. Principle of operation The compression in a screw compressor takes place by means of high speed rotors drawing coolant into the rotor grooves of the opposing rotor teeth. They transport the volume, that is steadily reduced and so it is compressed, from suction pressure to condensing pressure. The pressure at the additional middle connection (economised port) is similar to the intermediate pressure with a two-stage system. As a result of these features, a screw compressor of this design can be combined with an additional sub-cooling circuit for “two stage of compression”. These measures result in increased refrigeration capacity due to additional sub-cooled liquid entering the evaporator. The power consumption of the compressor increases only slightly when compared to the additional cooling performance.

Hitema’s microprocessor control systems perform real-time surveillance and prevention strategies. All the main functions of Hitema units are protected against irregular or potentially harmful operating conditions. This safeguard simplifies troubleshooting operations and minimizes maintenance times.

• EC CONDENSER FANS All condensate-air series, available in direct or indirect free-cooling configuration, use semi-screw compressors automatically controlled to give stepless capacity control, an economizer that increases the power cooling performance by 15%, condensing “EC-FANS” electronically switched that allow considerable acoustic and energy advantages, an electronic valve-rolling “EEV” and optimization of logic control through micro-processor. This ensures energy savings up to 50% of electricity consumed power and precision on water outlet temperature that other traditional systems can not reach. The constant pump flow rate to vary pressure provides interesting values of energy savings.

high energy efficiency that provides a substantial reduction in energy consumption, has led to decrease in the equipment CO2 foot print. The use of ecological refrigerants further help to raise the environemtal credentials of the products range. • QUALITY GUARANTEE Hitema’s guarantee of quality and reliability is underpinned by the use of the very latest technology supported by constant research and products that are manufactured in accordance with very stringent standards. • PERSONAL TRAINING 3000

• HEATING RECOVERY Partial or total condensing heat recovery generates hot water to different application requirements: - residential - industrial - commercial - technology installations

• PROPORTIONAL ELECTRONIC EXPANSION VALVE “EEV” Using electronic expansion valves is to have substantial economic benefits when there are variation in heat load and at different external conditions. Its use is due to accurate design decision closely related to refrigeration circuit and to optimization of functioning in various operating conditions Electronic thermostatic valve combined with condensing pressure control gets a further energy savings

The economizer is a device designed to improve both cooling capacity and efficiency of the system, by providing an additional sub-cooling, achieved with the addition of an intermediate plate heat exchanger, expansion valve and the cross flow refrigerant circuits. Principle of operation The compression in a screw compressor takes place by means of high speed rotors drawing coolant into the rotor grooves of the opposing rotor teeth. They transport the volume, that is steadily reduced and so it is compressed, from suction pressure to condensing pressure. The pressure at the additional middle connection (economised port) is similar to the intermediate pressure with a two-stage system. As a result of these features, a screw compressor of this design can be combined with an additional sub-cooling circuit for “two stage of compression”. These measures result in increased refrigeration capacity due to additional sub-cooled liquid entering the evaporator. The power consumption of the compressor increases only slightly when compared to the additional cooling performance.

Hitema’s microprocessor control systems perform real-time surveillance and prevention strategies. All the main functions of Hitema units are protected against irregular or potentially harmful operating conditions. This safeguard simplifies troubleshooting operations and minimizes maintenance times.

• EC CONDENSER FANS All condensate-air series, available in direct or indirect free-cooling configuration, use semi-screw compressors automatically controlled to give stepless capacity control, an economizer that increases the power cooling performance by 15%, condensing “EC-FANS” electronically switched that allow considerable acoustic and energy advantages, an electronic valve-rolling “EEV” and optimization of logic control through micro-processor. This ensures energy savings up to 50% of electricity consumed power and precision on water outlet temperature that other traditional systems can not reach. The constant pump flow rate to vary pressure provides interesting values of energy savings.

high energy efficiency that provides a substantial reduction in energy consumption, has led to decrease in the equipment CO2 foot print. The use of ecological refrigerants further help to raise the environemtal credentials of the products range. • QUALITY GUARANTEE Hitema’s guarantee of quality and reliability is underpinned by the use of the very latest technology supported by constant research and products that are manufactured in accordance with very stringent standards. • PERSONAL TRAINING 3000

• HEATING RECOVERY Partial or total condensing heat recovery generates hot water to different application requirements: - residential - industrial - commercial - technology installations

• PROPORTIONAL ELECTRONIC EXPANSION VALVE “EEV” Using electronic expansion valves is to have substantial economic benefits when there are variation in heat load and at different external conditions. Its use is due to accurate design decision closely related to refrigeration circuit and to optimization of functioning in various operating conditions Electronic thermostatic valve combined with condensing pressure control gets a further energy savings

The economizer is a device designed to improve both cooling capacity and efficiency of the system, by providing an additional sub-cooling, achieved with the addition of an intermediate plate heat exchanger, expansion valve and the cross flow refrigerant circuits. Principle of operation The compression in a screw compressor takes place by means of high speed rotors drawing coolant into the rotor grooves of the opposing rotor teeth. They transport the volume, that is steadily reduced and so it is compressed, from suction pressure to condensing pressure. The pressure at the additional middle connection (economised port) is similar to the intermediate pressure with a two-stage system. As a result of these features, a screw compressor of this design can be combined with an additional sub-cooling circuit for “two stage of compression”. These measures result in increased refrigeration capacity due to additional sub-cooled liquid entering the evaporator. The power consumption of the compressor increases only slightly when compared to the additional cooling performance.

Hitema’s microprocessor control systems perform real-time surveillance and prevention strategies. All the main functions of Hitema units are protected against irregular or potentially harmful operating conditions. This safeguard simplifies troubleshooting operations and minimizes maintenance times.

• EC CONDENSER FANS All condensate-air series, available in direct or indirect free-cooling configuration, use semi-screw compressors automatically controlled to give stepless capacity control, an economizer that increases the power cooling performance by 15%, condensing “EC-FANS” electronically switched that allow considerable acoustic and energy advantages, an electronic valve-rolling “EEV” and optimization of logic control through micro-processor. This ensures energy savings up to 50% of electricity consumed power and precision on water outlet temperature that other traditional systems can not reach. The constant pump flow rate to vary pressure provides interesting values of energy savings.

high energy efficiency that provides a substantial reduction in energy consumption, has led to decrease in the equipment CO2 foot print. The use of ecological refrigerants further help to raise the environemtal credentials of the products range. • QUALITY GUARANTEE Hitema’s guarantee of quality and reliability is underpinned by the use of the very latest technology supported by constant research and products that are manufactured in accordance with very stringent standards. • PERSONAL TRAINING 3000

• HEATING RECOVERY Partial or total condensing heat recovery generates hot water to different application requirements: - residential - industrial - commercial - technology installations

• PROPORTIONAL ELECTRONIC EXPANSION VALVE “EEV” Using electronic expansion valves is to have substantial economic benefits when there are variation in heat load and at different external conditions. Its use is due to accurate design decision closely related to refrigeration circuit and to optimization of functioning in various operating conditions Electronic thermostatic valve combined with condensing pressure control gets a further energy savings

The economizer is a device designed to improve both cooling capacity and efficiency of the system, by providing an additional sub-cooling, achieved with the addition of an intermediate plate heat exchanger, expansion valve and the cross flow refrigerant circuits. Principle of operation The compression in a screw compressor takes place by means of high speed rotors drawing coolant into the rotor grooves of the opposing rotor teeth. They transport the volume, that is steadily reduced and so it is compressed, from suction pressure to condensing pressure. The pressure at the additional middle connection (economised port) is similar to the intermediate pressure with a two-stage system. As a result of these features, a screw compressor of this design can be combined with an additional sub-cooling circuit for “two stage of compression”. These measures result in increased refrigeration capacity due to additional sub-cooled liquid entering the evaporator. The power consumption of the compressor increases only slightly when compared to the additional cooling performance.

Hitema’s microprocessor control systems perform real-time surveillance and prevention strategies. All the main functions of Hitema units are protected against irregular or potentially harmful operating conditions. This safeguard simplifies troubleshooting operations and minimizes maintenance times.
