Varm Commercial Duo Series

Overview

The Commercial Duo Series is Varmeks' large-capacity air-to-water heat pump for hotels, apartment blocks, commercial buildings and central plant rooms, offered in 50 kW and 92 kW versions. Built on natural refrigerant R290, it delivers space heating, cooling and domestic hot water from a single platform, with modulating heating capacity of 18.4-49.25 kW on the 50 kW unit and 35.2-92 kW on the 92 kW unit.The Commercial Duo Series is Motiontec Energy's large-capacity air-to-water heat pump for hotels, apartment blocks, commercial buildings and central plant rooms, offered in 50 kW and 92 kW versions.

Operating water temperature reaches 78 °C for both heating and DHW, allowing the Duo to feed high-temperature distribution systems and legionella-safe hot water storage, and the units keep running down to -25 °C ambient (range -25 to 43 °C). Rated heating COP is 3.8-4.3 (50 kW) and 3.86-5.02 (92 kW), DHW COP climbs to 5.62, and hot water output is 1,462 or 2,580 L/h. In cooling mode the units deliver 13.8-34.5 kW and 25-66 kW at EER 2.1-2.8.

HIGHLY compressors, R290 charges of 4.0 kg and 8.0 kg, IPX4 protection and 380-415 V three-phase supply are standard. Sound power is limited to ≤77 dB(A) and ≤85 dB(A) (sound pressure ≤62 and ≤65 dB(A)). Wi-Fi/IoT control allows remote monitoring and management, and multiple units can be cascaded for larger loads, as shown in Varmeks' reference installations.HIGHLY compressors, R290 charges of 4.0 kg and 8.0 kg, IPX4 protection and 380-415 V three-phase supply are standard.
