High Performance Heat Exchanger
HRW heat exchangers are refrigerant free and use no compressor. This energy efficient design saves further by using an inverter pump for demand-based rotation control. Four models offer cooling capacities from 2 to 30 kW. The HRW is rated for high performance temperature stability of ±0.3°C through a set range of 20 to 90°C. The operation panel includes an input keypad and multi-line LCD display. 23 alarms report on a variety of circuit and equipment conditions to facilitate optimal operation. In addition to standard I/O and RS-485 serial communications, analog and DeviceNetTM communications are optional.
HRW, High Performance Heat Exchanger
The HRW is commonly used by engineers in the semiconductor, medical, and laser industries who need to maintain an exact, stable temperature for sensitive equipment (like etchings tools or laser generators) without the noise, vibration, or energy cost of a traditional compressor-based industrial chiller. It uses copper or nickel-brazed heat exchangers and stainless steel piping to prevent corrosion. It includes an inverter pump for demand-based circulation control.

HRW Core Function & Performance
-
Temperature Range: 20°C to 90°C (68°F to 194°F).
-
Stability: High-precision control with a stability of ±0.3°C.
-
Process Cooling Capacities: Available in four main sizes: 2 kW, 8 kW, 15 kW, and 30 kW.
-
Mechanism: It removes heat by direct exchange between a circulating fluid and facility water. Because it lacks a refrigeration circuit, it significantly reduces power consumption (up to 59% compared to conventional chillers)
HRW Key Features
-
Inverter Pump: The "HS" models include an inverter pump that adjusts its speed based on demand, which can reduce energy use by up to 89%.
-
Fluid Compatibility: It is designed to work with specialized fluids including Fluorinated liquids (like Galden or Fluorinert), Ethylene glycol solutions (60%), and Deionized/Tap water.
-
Space-Saving Design: Features a "rear exhaust" design, meaning it doesn't need ventilation space on the sides. This allows multiple units to be placed side-by-side to save floor space.
-
Automatic Fluid Recovery: Includes an optional function (Option Z) to automatically recover the expensive circulating fluid from the customer's equipment back into the chiller's tank during maintenance, reducing waste and spill risk.
