Industrial Unit Coolers
CAPACITIES AND APPLICATIONS 
Newly designed cubic and dual flow industrial unit coolers, suitable for all applications and HFC and HCFC refrigerants. 
The capacities, air flow and electric ratings are declared, verified and certified according to the ENV 328 norms by the laboratories of the TÜV- Technische Überwachung Verein Institute in Bavaria, Germany. 
 
HEAT EXCHANGER COIL 
The heat exchanger coil is produced using a new geometry designed specifically for refrigeration, with high efficiency corrugated surface “TK” aluminium fins and 1/2“ diameter copper tubes internally grooved for direct expansion (D) and 5/8” diameter for pump operation (P) and flooding (N). 
The coil is tested to 30 bar, and all of its components are checked in accordance with the company’s stringent production specifications and quality control requirements. 
 
IHT, IMT e ILT series Industrial unit coolers: 
IHT series: fin spacing 4,5mm for high temperatures 15 ÷ 2°C 
IMT series: fin spacing 7mm for medium temperatures 2 ÷ -20°C 
ILT series: fin spacing 11mm for low temperatures -18 ÷ -35°C 
 
DHS, DMS, DHL e DML series double flow industrial unit coolers: 
DHS/DHL series: fin spacing 4,5 mm for high temperatures 15 ÷ 2°C 
DMS/DML series: fin spacing 7 mm for medium temperatures 2 ÷ -20°C 
All the unit coolers are pre-charged with dry air in order to ensure that the refrigerant circuit is free of humidity and perfectly clean. 
 
CASING 
The casing is manufactured in aluminium, protected and constructed in order to provide maximum strength and simple interchange with different operating and defrosting systems available. The casing made of STAINLESS STEEL AISI 304 is available on request. 
 
FANS 
All models use double speed three-phase 50 Hz fans with IP54 protection and internal thermalcontact.  
The DHS/DMS series use high speed delta connection fans (4 poles). 
The DHL/DML series use low speed star connection fans (6 poles). The effective performance in star mode is equal to Qn x 0,82. 
Single-phase, single speed fan-motors and for 60Hz are available on request.
