The unit uses the natural refrigerant R290, which is propane. Its global warming potential is only 3 and it has no ozone depletion potential. This makes the pump an eco-friendly and future-proof choice that complies with the requirements of the F-gas regulation.<\/p>\n<p dir=\"ltr\">Full inverter technology smoothly regulates compressor and fan operation according to the actual heat demand. The result is a stable water temperature, lower energy consumption, and a longer equipment lifespan. EVI technology ensures good heating output and efficiency even in cold weather, and the pump operates stably down to an outdoor temperature of \u221235 \u00b0C.<\/p>\n<p dir=\"ltr\">The outgoing water temperature reaches up to 75 \u00b0C. Therefore, the pump is suitable for underfloor heating and fan coils as well as traditional high-temperature radiators. In summer, the unit can be used for cooling when the outgoing water temperature is 7\u201325 \u00b0C.<\/p>\n<p dir=\"ltr\">The heat pump produces domestic hot water up to 75 \u00b0C, and the temperature can be set by the user via the controller. The built-in high-temperature sterilization function protects the domestic hot water against Legionella bacteria.<\/p>\n<p dir=\"ltr\">Nominal heating capacity (A7\/W35) ranges from 18.5 to 50.5 kW with a COP of up to 4.70. The compact casing with a single compressor and a single fan, measuring 1100 \u00d7 1100 \u00d7 2150 mm, is well-suited for installation in confined spaces. The noise level starts from 39 dB(A).<\/p>\n<p dir=\"ltr\">Operating modes:<\/p>\n<ul dir=\"ltr\">\n<li>heating with radiators and fan coils<\/li>\n<li>underfloor heating<\/li>\n<li>cooling<\/li>\n<li>domestic hot water production (up to 75 \u00b0C)<\/li>\n<\/ul>\n<p dir=\"ltr\"><strong>Features<\/strong><\/p>\n<ul dir=\"ltr\">\n<li>Model: WESTON-GH-MN-R290-50KW-3F<\/li>\n<li>Power supply: 380\u2013415 V \/ 3N \/ 50 Hz<\/li>\n<li>Heating capacity (A7\/W35): 18.50\u201350.50 kW<\/li>\n<li>Power input (A7\/W35): 3,95\u201314,80 kW<\/li>\n<li>COP (A7\/W35): 3.5\u20134.70<\/li>\n<li>Heating capacity (A7\/W55): 10,85\u201340,00 kW<\/li>\n<li>Power input (A7\/W55): 3,74\u201313,79 kW<\/li>\n<li>COP (A7\/W55): 3.02\u20133.52<\/li>\n<li>Cooling capacity (A35\/W7): 10.15\u201328.50 kW<\/li>\n<li>Cooling power input: 3.63\u201312.95 kW<\/li>\n<li>EER: 2.20\u20132.70<\/li>\n<li>Maximum input power: 19.3 kW<\/li>\n<li>Maximum current: 35.0 A<\/li>\n<li>ErP energy rating (35 \u00b0C \/ 55 \u00b0C): A+++ \/ A++<\/li>\n<li>Refrigerant: R290, 3.1 kg<\/li>\n<li>Maximum allowable pressure: 3.2 MPa<\/li>\n<li>Number of compressors: 1<\/li>\n<li>Number of fans: 1<\/li>\n<li>Fan motor: DC<\/li>\n<li>Electronic expansion valve: (EEV)<\/li>\n<li>Airflow direction: vertical<\/li>\n<li>Protection class: IPX4<\/li>\n<li>Electrical safety class: I<\/li>\n<li>Water flow rate: 6.0 m\u00b3\/h<\/li>\n<li>Water pressure drop: 65 kPa<\/li>\n<li>Operating temperature range: \u221235\u202646 \u00b0C<\/li>\n<li>Outlet water temperature (heating): 20\u201375 \u00b0C<\/li>\n<li>Supply water temperature (underfloor heating): 20\u201350 \u00b0C<\/li>\n<li>Leaving water temperature (cooling): 7\u201325 \u00b0C<\/li>\n<li>Domestic hot water temperature: up to 75 \u00b0C<\/li>\n<li>Sterilization function: yes (Legionella protection)<\/li>\n<li>Noise level: 55 (39\u201355) dB(A)<\/li>\n<li>Vee\u00fchendus: G1\u00bd&#8221; (G3\/2)<\/li>\n<li>Net weight: 450 kg<\/li>\n<li>Dimensions (L \u00d7 W \u00d7 H): 1100 \u00d7 1100 \u00d7 2150 mm<\/li>\n<li>Package dimensions: 1144 \u00d7 1144 \u00d7 2250 mm<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Weston Climate Pro R290 industrial air-to-water heat pump with a capacity of up to 50.5 kW.
