Remko Air conditioning chilled water KWP 405 1703315

Chilled water generator with heat pump function in modular compact design for outdoor installation, ready for connection, air-cooled. Weather-resistant base frame with removable cladding panels made of powder-coated sheet steel, colour similar to RAL 9018. Condenser and sound-insulated compressor compartment separated from each other.
Air inlet via large-area high-performance condenser (cooling mode) in straight design made of refrigeration copper pipe with positive-locking aluminium fins. Air outlet via flow-optimised, statically and dynamically balanced axial fan(s) with protective cage. Standard operating limits in cooling mode between +45°C and -7°C, range can be extended down to -15°C with winter pressure control accessory. Operating limits in heating mode between +20°C and -10°C. Two fully hermetic, vibration-damped scroll compressors with refrigerating machine oil filling, optimally controlled according to the operating times. Crankcase heater(s) for compressor(s) as standard.
One refrigerant circuit made of refrigeration 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, pressure transmitters on the high and low pressure side, filter dryer and thermostatic expansion valve with external pressure equalisation. Evaporator (cooling mode) as refrigerant/water heat exchanger in brazed plate design made of stainless steel, vapour diffusion-tight insulation, return temperature range from +18°C to +10°C in cooling mode and +30°C to +48°C in heating mode.
Insulated medium circuit for water/glycol mixtures made of steel pipe with filling and draining connection, manual air vent valve and differential pressure switch for monitoring the volume flow. Medium connections in inch Victaulic design.
Control box with terminal strip for mains supply, potential-free input for external release, potential-free output for collective fault signal and connection of a cable remote control. Fully wired and tested main and control circuit with phase sequence relay, circuit breaker, fuses, contactors for main and control circuits and transformers fitted as standard. Automatic restart after power failure.
Easily accessible microprocessor controller with Modbus (RS485) and USB interface for independent monitoring and control of all operating functions, protected from environmental influences and based on Linux. User-friendly display of all control parameters and coded fault messages within a value and parameter display, e.g. medium inlet and outlet temperatures, operating pressures in the refrigeration circuit. Function display of the operating modes, fan, compressors, circulation pump and collective fault.
Operation of the device using six operating buttons. Three password-protected parameter areas available.
Compliance with all requirements of the Ecodesign Directive through optimised heat exchanger surfaces, use of high-efficiency components and optimisation of the system parameters relevant to operation.

The regional regulations or ordinances or environmental protection laws, e.g. WHG, must be taken into account when planning and installing the appliances.
