KHS CoolFlow Chiller

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
• *air inlet temperature 35°C dry bulb, medium temperatures 7/12 °C, 0% glycol concentration
