Cranberry Township, Pa. — The latest EP2 series portable chillers from auxiliary equipment supplier Conair Group include a programmable logic control (PLC) and a seven-inch color touchscreen human-machine interface as standard equipment with air-cooled, water-cooled, or remote air-cooled condensers.
The chillers use a new sloped top electrical panel that places the large touchscreen on the front of the unit at a height and angle for easy viewing and operation.
New capabilities include digital pump pressure display, compressor/pump/fan running hours, and performance trend charts for key operating parameters such as process fluid temperatures.
The new controls also include Modbus RTU communications as standard for easy integration of the chillers with injection molding machine controls or plant-wide process monitoring systems.
In addition, the new control system is fully compatible with Conair's cloud-based Industry 4.0 solution for auxiliary equipment monitoring, management, and analysis known as the SmartServices platform.
An optional premium EP2 control system provides an expanded PLC system with additional communications capabilities, such as Modbus TCP/IP, BACnet MS/TP, BACnet/IP, LonWorks and OPC/UA.
For flexibility under different part-load conditions, the EP2 chillers offer variable-speed Scroll compressors technology options on 5-, 10-, 15-, 20-, and 30-ton water-cooled and air-cooled chillers. The compressor speed adjusts automatically so the chillers work only as hard as necessary to perform with significantly reduced power use.
EP2 air-cooled units are equipped with micro-channel condensers designed for industrial environments while the water-cooled units use cleanable shell-and-tube condensers and have a condenser-water regulating valve to provide constant head pressure. The remote condenser units are available to direct all heat outside the building.
Conair Group says all EP2 chillers meet severe-duty industrial cooling needs and resist harsh fluid conditions and operating environments. They feature stainless steel pumps and evaporators as well as a process-fluid circuit with corrosion-resistant materials to prevent rust and ensure clean, dependable operation.
