AWK EVI Urban MonoBlock

High temperature compact outdoor monoblock heat pump air - water

Compact outdoor air - water heat pump in monoblock style with scroll compressor and condenser heat exchanger in outdoor unit. Indoor HydroBox or ControlBox is available to complement the system. With stable frame construction. Double high-absorption suspension with sylomer pads and adjustable base plates ensure low noise and vibration levels of the Scroll compressor.

Stainless steel plate heat exchanger (1,4401) for heating circuit. Free-hanging Al-Cu V-shaped heat exchanger with water resistant coating in the outdoor unit. Electrical switchboard with integrated safety elements and equithermal controller of the heat pump is located below the upper lid in the indoor unit. Quiet, low-speed EC Ziehl - Abegg with bionic fins on top of the outdoor unit. Easy and quick installation and commissioning. Easy cabling with RJ45 Plug-in system.

Full stainless bodywork for units over 20 kW of nominal heating capacity ( outdoor unit type AWK-900 ) for outdoor installation. Epoxide coating for outdoor units below 20 kW of nominal heating capacity ( outdoor unit type AWK-600 ). Reversible defrosting optimized via APS system with subcooling of liquid refrigerant. With electronic starter via built-in soft starter and electronic expansion control with autoadaptivity.

Frame construction with a massive base plate on adjustable legs. Covering the epoxy-coated unit. The multi-layer sound insulation and vibration-eliminating profiles are glued from the inside of the cover. Equithermal, digital control of the heat pump with integrated cooling control function. For controlling one heating or cooling circuit with mixing unit, for one heating or cooling circuit without a mixing unit. Temperature regulation for DHW storage tank and control of electrical backup heating elementnt inside the heat pump. Simple extension of control up to 3 heating / cooling circuits via expansion modules or up to 16 circuits via system controllers. The standard version also includes solar control as well as the possibility of cascading up to 16 devices.

Full-text control menu with features dependent on user instructions, information texts and status output signal. Diagnostic system with record history of operation. External temperature sensor, hotgas sensor, liquid refrigerant temperature sensor, heat pump flow and return temperature sensor as well as source output sensor, source return sensor, and hot water sensor.

Optionally available with ModBus module as well WebControl control and monitoring via the Internet.
