Comfort Flex Vertical Fan & Coil feature several options to mitigate mold and mildew when applied in a properly designed and constructed building. For humid climates, Comfort Flex offers innovations to ensure optimum humidity control at part load conditions.

The Clima-Flex units are pioneer in the VRW technology.

The most important advantage is the modulation of the 2 way chilled water valve together with the EC motor fan to maintain the proper flow while maintaining the chilled water temperature through the coil at minimum CFMs required to have a continuous dehumidification needed.

The inorganic film on the surface is ultra thin and is formed by an inert ceramic glass layer that is obtained at ambient temperatures. This innovative technology provides:

(OPTIONAL)

• UV resistance • A crystalline finished, non-yellowing • Positively charged coating to repel H2O • Magnificent luster and depth of image retention • Outstanding resistance to solvents and chemicals • Exceptional abrasion resistance

• ENERGY EFFICIENT

With ADSIL you save energy between 9% to 15%. Its sealant layer of only 3-5 microns allows heat transfer be more efficient.

• EXTENDS THE LIFE OF THE EQUIPMENT

ADSIL extends the life of your air conditioner units, refrigerators or cooling towers, because it protects up to 5 years, preserving its appearance and function.

ADSIL is applied to cabinets, capacitors, grids and coils, achieving great benefits and durability that can not be obtained with conventional protections.

Protects both the coil and the coil bypass air from airborne contaminants. Filter frame and media are non-organic, and will not support mold growth.

INNOVATIVE TEMPERATURE AND HUMIDITY CONTROLLER (MODBUS ENABLE) Improves part load relative humidity control.

STAINLESS STEEL DRAIN PANS AND COIL CASINGS

Are available for use where added corrosion resistance or longevity are required.

Coils and piping packages are removable in minutes through the standard front panel with only a screwdriver and pair of wrenches for periodic cleaning or service outside of the unit.

ELASTOMERIC CLOSED CELL FOAM INSULATION Is a great alternative to fiberglass insulation in extremely humid climates, as

well as hirise residential facilities. The material’s smooth and cleanable surface makes it naturally mold resistant, with no danger of fibrous material entering the airstream. Additional features include: • Easily cleaned surface resists dirt, moisture absorption, and microbial growth – even if torn or punctured.

• Higher temperature limit than polyethylene CCF, able to withstand service temperature spikes without permanent failure.

• More flexible than polyethylene CCF at 75°F, allowing expansion and contraction in hot and cold cycle applications.

• Compression resistance; retains its thermal insulating capacity.

• Outer moisture vapor barrier or liner not required.

IAQ DRAIN PAN

Is double sloped to prevent standing water. An optional drain pan is removable for effective cleaning.

Comfort Flex offers Vertical Fan & Coil with EC motors. EC Motors significantly increases the operating efficiency of Comfort Flex fan coils, they also provide different control and performance capabilities. For each motor, fan speed control is accomplished through a microprocessor based controller that electronically controls the speed of the motor. These motors provide peak efficiency ratings between 70 & 80% for most applications.

The first, full featured, EC motor offers continuously variable speed operation, constant airflow. This is achieved via proportional control from a remote 2 – 10V DC signal

ECM FEATURES AND BENEFITS

21

• ULTRA- HIGH MOTOR & CONTROLLER ENERGY EFFICIENCY EC motors offer several advantages over PSC motors in fan Coils, including variable speed, constant CFM or constant Torque operation, and significantly higher efficiency. Due to the Permanent magnet rotor and electronic commutation, the EC Motor maintains approximately 75% efficiency at all speeds.

Unlike a sleeve bearing motor, the ECM does not have a minimum RPM requirement for bearing lubrication. This allows it to operate over a much wider speed range, and provides for maintenance – free operation. A reduced spare parts inventory is another plus.

• EXTENDED MOTOR LIFE

The high motor efficiency provides a significantly reduced operating temperature compared to an induction motor. The lower temperature increases the longevity of all electrical components and therefore the life of the motor. The ball bearings do not require lubrication and do not adversely impact the motor life. Expected ECM life will be considerably longer than a PSC motor, due to the reduced operating temperature and ball bearing components.

• Visually appealing Sleek sophisticated design with touch screen display.

• TECHNICAL DATA • Power 24VAC power from a UL Listed Class-2 24VAC transformer (not provided). The VLD-362W uses a half-wave rectifier to convert the AC power supply to onboard power. This enables multiple devices with half-wave power supplies to be powered from a single, grounded transformer.

Min. Load = 17VA (all BOs OFF).

Max. Load = 89VA (all BOs ON).

If BO power jumper is not removed, then all BOs are powered from the controller’s transformer.

All BOs are N.O. (Normally Open) contacts with a maximum switch rating of 24VAC @ 0.5A (12VA).

Maximum load assumes all 6 binary output loads are powered from the controller transformer and connected loads are the maximum allowed (24VAC @ 0.5A).

Actual power requirements depend on connected loads.

• Wireless Receiver: (VLD-362-FF-W version only) 433.92 Mhz; range is 50 feet.

• Inputs: 3 universal inputs with 12-bit accuracy, providing controlled voltage, current and resistive modes.

• Internal Sensors: 1 internal temperature sensor, 0–120 deg. F (-17.8–48.9 deg. C); 1 internal humidity, 5–95% RH, non-condensing.

• Binary Outputs: 6 relay outputs; normally open contacts with a máximum switch rating of 24VAC @ 0.5A (12VA). BO-0, BO-2 and BO-5 are powered from the controller transformer. BO-1, BO-3 and BO-4 are powered from control transformer through removable jumper, allowing these BOs to be powered from a separate power source.

• Universal Analog Outputs: 2 outputs with 12-bit resolution. Each auto-detects for 0–10VDC or 4–20mA. 4–20mA outputs are sourced by the VLD. Connected loads must return to the VLD ground. The VLD-362W automatically switches from 0–10V mode to 4–20mA current mode when it detects a load value of less than 500 Ohms.

• Processor & Memory: Powerful 32-bit processor with extensive flash memory and RAM resources. Flash memory provides nonvolatile program and data storage, and allows for encrypted updates to the program for future product enhancements.
