The Helpman TYR 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 TYR models have been highly standardised in construction and dimensions, while maintaining flexibility in fin spacings, coil construction and circuiting design.
Air coolers and air-cooled condensers are key components in air cooling and air conditioning systems. On the refrigerant side the most common media are a brine or an evaporating refrigerant like HFO/HFC, ammonia or CO2. A chilled brine may be supplied from a chiller that is potentially located far away, but a liquified refrigerant must come from a nearby condensing unit. When an evaporating refrigerant is used, the cooling coil is the evaporator in the vapour-compression refrigeration cycle (‘direct expansion’ or ‘DX’ system).
