Remko Air conditioning cold water RVS 220 DC 1611677

Air-cooled chiller in compact design for outdoor installation with infinitely variable capacity control for cooling and heating.
Weather-resistant base frame with removable cladding panels made of powder-coated steel, colour similar to RAL 9010. Condenser and sound-insulated compressor compartment separated from each other. Air inlet via large, efficiency-optimised high-performance condenser in corner design made of refrigeration copper pipe with specially finned aluminium fins to increase the heat exchanger surface and condenser protection grille. Air discharge through aerodynamically optimised, statically and dynamically balanced axial fans with protective cage. Modern EC fans and integrated fan control to reduce operating costs and optimise the fan speed to the respective ambient conditions. Infinitely variable speed control through thermal low-noise fan control for particularly low noise emissions. Standard operating limits in cooling from -15°C to +45°C, in heating from -30°C to +43°C thanks to standard EVI injection. 1 fully hermetic, vibration-damped inverter compressor in rolling piston design for infinitely variable adjustment of the compressor frequency, with refrigeration machine oil filling. Refrigerant circuit made of refrigerant copper pipe, hermetically sealed and pressure-tested at the factory, dried and filled with R410A safety refrigerant. Control option via Schrader valve. High and low pressure switches, filter dryer and electronic expansion valve to increase energy efficiency and improve control quality. Evaporator as refrigerant-water heat exchanger as shell and tube heat exchanger, vapour diffusion-tight insulation, return temperature range from +7 °C to +25 °C in cooling mode and from +25 °C to +60 °C in heating mode. Insulated medium circuit with manual air vent valve, differential pressure switch for monitoring the volume flow and speed-controlled circulation pump in accordance with the Ecodesign Directive. Medium connections in solid design with imperial internal thread. Internal switch box with terminal strip for mains supply, contact for external release, collective fault signalling contact and connection of a cable remote control. Fully wired and tested main and control circuit with transformer, control fuses to protect the appliance circuit board. Automatic restart after power failure. Modern touch controller in splash-proof IP54 housing for operating the appliance and setting other operating parameters. RS485 Modbus interface as standard. User-dependent input of the return temperature can be changed without a password. Clear value display of medium inlet and outlet temperature as well as function display of fan, compressor, required maintenance interval and elementary faults, e.g. high/low and differential pressure. Coded fault messages and display of all operating-relevant control parameters accessible with password protection.
Compliance with all requirements of the Ecodesign Directive (EU) 2016/2281 (LOT 21) thanks to optimised heat exchanger surfaces, use of high-efficiency components and optimisation of the system parameters relevant to operation.
