Product Features

for cooling the KHS CoolFlow cold water cooler
air-cooled chiller in compact design for outdoor installation for energy-efficient operation of the KHS CoolFlow cold water circulation
weatherproof base frame with removable cladding panels made of powder-coated steel, colour similar to RAL 9010
with infinitely variable cooling control
modern EC fans and integrated fan control to reduce operating costs and optimally adjust the fan speed to the actual ambient conditions
infinitely variable speed regulation through thermal low-noise fan control for particularly low noise emissions
standard operating limits from -15°C to +45°C
fully hermetic, vibration-damped rotating-piston inverter compressor for infinitely variable adjustment of the compressor frequency, with refrigerator oil filling
refrigerant circuit made of refrigerant copper pipe, hermetically sealed and pressure tested at the factory, dried and filled with R410A safety refrigerant
controllable via Schrader valve
High- and low-pressure control device, filter dryer and electronic expansion valve to increase energy efficiency and improve control quality
evaporator as refrigerant-water heat exchanger as tube bundle heat exchanger, vapour-diffusion-tight insulation, return temperature range from +10°C to +20°C
insulated medium circuit with manual bleeder valve, differential pressure monitor for monitoring the volume flow, and speed-controlled circulation pump according to the specifications of the Ecodesign Directive
medium connections in solid design with one-inch female pipe thread
internal control box with terminal strip for mains power supply, contact for external release and potential-free contact for collective fault signal
completely wired and tested main and control circuit with transformer, control fuses to protect the device’s PCB
automatic restart after power failure
modern touch controller in IP54 splash-proof body for operating the device and setting further operating parameters
RS485 Modbus interface as standard
clear display of medium inlet and outlet temperature as well as function display of fan, compressor, required maintenance interval and elementary faults, such as high/low and differential pressure
coded fault messages and display of all operation-relevant control parameters with password-protected access
compliance with all requirements of the Ecodesign Directive (EU) 2016/2281 (LOT 21) through optimized heat exchanger surfaces, use of high-efficiency components and optimisation of operationally relevant system parameters
