HEAT PUMPS AND REVERSIBLE UNITS

HTE heat pump exchangers are designed for the production of chilled water or heated water by reversing fluid side and air side to meet every need of installation and management of the plant. The focus is on the energy consumption of air conditioning equipment, HVAC systems and hygrometric comfort too, is becoming increasingly important. That's why the ventilated the HTE units for heat pump application are designed to provide maximum energy efficiency at both, full load EER and partial load ESEER. The circuiting is already designed and optimized for these operating conditions. This is a good indicator to understand how HTE actively pursues the policy of energy saving.

A wide range of products and possible configurations of heat pump exchangers: [Table], [V-Form] [Magnum], [H-Flow], [Jumbo], [X-cross] and customized products as well. The construction can be in mono and multi-bank, further customization functional to your needs allows you to find the best balance between thermal capacity conditions, acoustic performance and systemic solutions, guaranteed by the usual HTE quality.

We offer special versions of compact space-saving fans, applications with high voltage, 60 Hz, EC brushless and special versions according to ATEX regulations. You can profit from solutions for OEM´s or the B2B market to reduce the construction lead-time of the water chiller, both for the production of domestic hot water or cold water as needed. Exchangers with geometries suitably designed for low pressure drops on the air side, reducing the formation of ice on the fins and consequently reducing the by-pass factor, obtaining an improvement of the efficiency and of power consumption.

Equipment and accessories can be integrated on request.

ADVANTAGES OF HEAT PUMPS:

• ENVIRONMENTALLY FRIENDLY: The heat pump technology is clean, has no direct CO2 emissions. 
• ECOLOGICAL: The driving energy of the heat pumps is only electric energy consumption. 
• Large heat exchange surface 
• High ESEER (Eurovent benchmark for partial loads) 
• Annual energy consumption is lower than 50% compared to traditional heating systems 
• Noise reduction with electronically commutated EC fans (optional) 
• Compact and space-saving versions available
• Centralized supervision (Optional)

Fans

All H.T.E. units are equipped with high efficiency multiple wing fans according to the eco-compatible directive UE nr. 327/2011. The electric motors are thermally protected with IP54 protection class, IP55 according to IEC/EN 60529/ DIN 40050. The axial fans with external rotor are of the service-free type, with hermetic bearings according to DIN 6252 with lifetime lubrication, statically and dynamically trimmed according to ISO 1940/1. The windings have different isoltation class, varying between the standarf F class, up to H class for particularly demanding applications. The functionning limits are between -30°C and +60°C for the standard motor configuration. Other motors are available upon request. The three-phase motors are ready for the double connection (star, delta or with switching device). All fans motors are designed to be connected to a tension or a frequency regulation device, to control rotation speed and noise level. There are 5 different performance sizes at disposal, ensuring excellent performances through the combination of installed power, noise level and respect of the declared consumption.
Optional	• Cabled fans ready for the connection on a contact board according to EN 60204-1 rule; • 60Hz versions; • Special voltages; • According to ATEX-regulations; • In pushing or reversible version; • With EC-bruschless electronic modulating motors; • Centrifugal fans; • Regulation systems; • HTE Process Control Manager
According to the type of ventilator the motor data may vary. Please remark that the energy consumption will vary in function of the air temperature and the load conditions. We reserve ourselves the right to use fans made by different manufacturers. For the corresponding specific electrical data refer yourself to the type of unit or fan model.
