FRIMETAL

Dual discharge for ammonia

TNH Series

Nominal Capacities between 33,4 and 163 kW

Dual discharge evaporators designed for use in fast cooling tunnels of medium or low temperatures where high air pressure is required, together with perfect air distribution through the product located on the pallets.

Manufactured with stainless steel tubes with options AISI-304L or AISI-316L expanded over aluminium fins.

Design to work with refrigerant ammonia pumped, gravity feeding or direct expansion DX system. These units can also work with other refrigerants (R-404A, water-glycol, etc.) as an alternative to the standard copper tube models GR when the ambient condition inside the cold room is harmful for copper.

The evaporator must placed in the centre of the tunnel ceiling and must occupy the entire length of the tunnel. The pallets holding the product must be located lengthways on both sides, separated by a central aisle for the air returning to the fans.
