Haier calling

Haier has released a new high-wall split-system air conditioner called Dawn.

The new unit has been tested in Australia to ensure it can cope across the country’s diverse climate.

“From the searing heat of the desert, to the humidity of the tropics, to the chill of Tasmania, Dawn will help you create an environment you’ll love to be in,” says the company.

Wi-fi connectivity is a standard feature. Dawn also offers voice control using Google Home, and can be activated remotely. Haier notes that the new system offers benefits for indoor air quality, too.

“Haier’s revolutionary patented self-clean technology freezes the indoor heat exchanger, trapping pollen and dust,” says the company. “It then defrosts, washing away the trapped contaminants and leaving your air conditioner to deliver clean, healthy air.”

Finally, Dawn is equipped with a smart movement and light sensor designed to sense motion over a large area and precisely locate any humans in the room. If no one is detected, the unit goes into sleep mode to conserve energy.

All the way with AWA

Armaturenwerk Altenburg (AWA), a European manufacturer of valves, sight glasses and fittings for refrigeration and air conditioning technology, has released a new oil-level-regulation system called OLC.

“The AWA OLC guarantees the optimum oil level in refrigeration compressors, and is used in compound systems with reciprocating or scroll compressors,” says the company. “Its functionality is essentially based on the almost infinitely variable level measurement by means of an electronic float sensor. It can be used in systems of up to 120 bar for a variety of refrigerants and oils, and ensures permanent and instantaneous level detection. In addition to the level, the speed of change of the level is also evaluated for the first time.”

According to AWA, the electronic float is insensitive to foaming and swashing oil. Other features include a large sight glass for better level recognition, an LED display on the front for fast status recording, and a modular adapter system for connection to all common compressor types. And the installation dimensions have been reduced by up to 25 per cent.

The AWA OLC also incorporates special autonomous electronics functions to protect compressors.

In control with Carel

Carel has released its pCO5+ HS (high-speed) programmable controller, designed to improve the efficiency of HVAC&R kit such as chillers, process chillers, and equipment in data centres.

“The new pCO5+ HS guarantees improved performance both in terms of application times – start-up and cycle – and upgrade speed,” Carel says.

“This improved controller performance translates into faster unit set-up. When commissioning in the field, system management is also much faster.

Carel says the calculation speed of the pCO5+ HS means it can respond more quickly and precisely to variations in the main unit input values in terms of temperature, pressure, and humidity.

The pCO5+ HS comes with two built-in serial interfaces, two expansion slots and two USB ports. The controller also features a wide range of optional cards for managing the communication protocols typically used in HVAC&R. Communication with Carel apps can also be implemented using 1tool.

The pCO5+ HS is available with two built-in electronic expansion valve drivers and an optional Ultracap module. This is designed for integrated energy saving management.

Go with the flow

Dwyer Instruments has recently released its series IEF Insertion Electromagnetic Flow Transmitter featuring electromagnetic technology.

Dwyer says the transmitter accurately and reliably measures fluid velocity in addition to providing several continuous signal outputs.

“This series is specifically designed to offer superior performance paired with simple installation and use,” Dwyer says. “One unit is adjustable to fit pipe sizes from 4 to 36" – 101.6 to 914.4 mm – and offers several output options including selectable BACnet MS/TP or Modbus RTU communications protocol over 2-wire RS-485 in addition to the standard analogue, frequency and alarm outputs.

“High-performance accuracy is maintained through temperature, density or viscosity.”

Dwyer says field-configurable, integral or remote set-up displays allow for flexibility by accommodating a variety of application configurations with one model through multiple display configurations such as pipe size and material through to calibration factor.

“A set-up wizard and installation tool are simple to use, allowing for quick and precise installation,” Dwyer says. “The IEF has long life-cycle and minimal maintenance requirements, with no moving parts to wear or break, and electrodes that discourage fouling.”

Fyrebox in effect

Since the Fyrebox Cast-In earned the AIRAH Product of the Year in 2018, it has had a number of changes.

Steel reinforcement channels have been added to give extra support to the box during concrete pour. And the Fyreboxes are now powder coated for extra durability.

“Fyrebox Cast-In … provides a single, compact, pre-formed fire-rated opening in floors that trades can run any number of mixed services through,” the firm says. “This is especially important for the HVAC&R industry, as it is common to have a large volume of services needing to be routed through a small footprint.

“By casting directly into the floor slab, Fyrebox Cast-In eliminates the need for core-drilling of holes or forming of openings, which saves HVAC&R trades time and money,” the company says.

“Fire tested and fully approved to AS1530.4 and AS4072.1, the Fyrebox Cast-In achieves a fire rating of up to four hours and offers an opportunity for HVAC&R trades to make passive fire compliance easier, ensuring life safety.”

Lend me your ears

Honeywell Industrial Safety (HIS) has introduced the Honeywell Howard Leight VeriShield 100 Series Passive earmuffs.

“From indoors to outdoors working with machinery, to the tools being operated and the processes taking place – all can be sources of harmful noise, and all require effective protection for workers,” HIS says. “The range of options offered ensures comfort and protection against any noise level, for every worker.”

The earmuffs have been designed with the construction, manufacturing, utilities, oil and gas, and medical industries in mind.

“The VeriShield range reduces the short- and long-term effects of hazardous noise on hearing, and are designed to provide optimum comfort over long periods of use,” HIS says.

“Key features include large dimension range, with 17 per cent more adjustability than earlier models, comfortably fitting a wide range of head sizes. Wide cup openings, with 16 per cent more opening manoeuvrability, are ideal for workers with larger ears or who wear hearing aids.

DO YOU HAVE A NEW PRODUCT TO GO IN THE TOOLSHED?

“The VeriShield 100 series spare no comfort, armed with lightweight cushioned headbands and memory foam ear cushions, offering denser and softer foam than previous models, for greater comfort and attenuation.”

The range includes three different models. ■

Airbitat in the habitat

Climate Rental Solutions has released the Airbitat Evaporative Cooler.

“The Airbitat is a revolutionary new product, which is designed to be 50 per cent more effective in delivering deeper cooling than conventional evaporative coolers by using its three-step Reevac deep-cooling technology,” Climate Rental Solutions says.

“The Airbitat operates from a standard power supply, attaches to a continuous water supply, is fully mobile on wheels, and covers an area of approximately 50–75m 2 .”

Developed and manufactured in Singapore, the units are distributed by Climate Rental Solutions on the east coast of Australia and South Australia, and by Safety Cool in WA.

“The Airbitat is self-cleaning,” Climate Rentals says. “Its web-based smart control system means it can be operated and monitored remotely, allowing for real-time performance data and settings adjustment.”
