General information & application
The Helpman THOR series is a wide and flexible range of
heavy-duty industrial air coolers for both cooling and freezing
applications in medium to large cold rooms. Suitable for a
wide range of applications, with a special focus on meat
storage, agricultural produce and packed products.
All THOR models have been highly standardised in
construction and dimensions, while maintaining flexibility in
fin spacings, coil construction and circuiting design.
Evaporating temp. +5 to -40°C
Refrigerants all H(C)FC, brine, CO2
Capacities (SC2) 5 up to 116 kW*
Air volume 4,000 up to 67,000 m3/h.
* Higher capacities on request

Test
Design pressure 33 bar, higher design pressures on request.
Each heat exchanger is leak tested with dry air and finally
supplied with a nitrogen pre-charge. Brine coolers are tested
at 6 bar.
