The compact CHP units of the 50 kW class built by SOKRATHERM for decades are most commonly found in operation. They are mainly installed in mid-sized hotels, swimming pools, district heating centers, schools and nursing homes. By integrating the switchgear inside the sound absorbing case SOKRATHERM was the first producer of compact ready-to-connect CHP units.
With its especially compact dimensions (l x b x h = 220 x 90 x 180 cm) the GG 50 VR is the smallest ready-to-connect CHP unit of the 50 kW class and makes the installation possible also in narrow heating centers. All CHP unit types of this power class are equipped in series with an intergrated heating water pump and return rise. The type GG 50 6VRS introduced in 2021 has additionally a 6 cylinder engine and an integrated system separation betreen the heating water circuits. By application of a condensing heat exchanger this type reaches up to 107 kW thermal power and up to 104 % total efficiency.
Prominent application examples are the installations in the Irish Cork Institute of Technology (CIT), the German-Polish district heating of Frankfurt a.d. Oder / Słubice
(article, German), the double CHP plant (GG 50 + GG 70) in the alpine hotel Zechmeisterlehen (article, German) and the GG 50 6VRS in the school center in Waldshut-Tiengen (article, German).
The CHPmobile variant is realized most frequently in this class. The CHP unit is mounted on a trailer and can be operated at two sites – for example, as the GG 50 mobile in Hemer (article, German), at an indoor swimming pool in the winter and at an outdoor swimming pool in the summer.
