EW-HT-Y 0152 - 0612

Water to water heat pumps, heating only, very high temperature water production 70,2 - 279 kW

EW-HT-Y represents the best solution for systems where very high temperature water is needed. The special compressor adopted grants hot water production up to 80°C and allows high evaporation temperature (evaporator leaving water temperature up to 40°C). The extraordinary operating limits ensure the perfect integration of the unit in any application, such as 4-pipe systems, industrial process heat recovery or district heating systems.

Features

WIDE OPERATING RANGE

Hot water production up to 80°C (evaporator water outlet up to 40°C).

MAXIMUM RELIABILITY

Unit with two independent refrigerant circuits, designed to ensure maximum efficiency at full load, ensuring uninterrupted operation even in the event of temporary stop of one of the two circuits.

ELECTRONIC EXPANSION VALVE SUPPLIED AS STANDARD

The use of the electronic expansion valve generates considerable benefits, especially in cases of variable demand and different external conditions. It was introduced into these units as a result of accurate design choices concerning the cooling circuit and the optimisation of operation in various different working conditions.

COMPACTNESS

Reduced dimensions, for easy installation even in sites with space´ constraints

Electronic control W3000TE

The W3000TE controller offers advanced functions and algorithms. The Compact keypad features an easy-to-use interface and a complete LCD display that allows consulting and intervening on the unit by means of a multi-language menu (19 languages are available). The regulation is based on the patented “Quickmind” water temperature regulation logic uses self-adapting control to maintain flow temperatures and optimise performance even in low water content scenarios. As an alternative, the proportional or proportional-integral regulations are also available. The diagnostics comprises a complete alarm management system, with the “black-box” (via PC) and the alarm history display (via display or also PC) for enhanced analysis of the unit operation Optional proprietary devices can perform the adjustment of the resources in systems made of several units. Consumption metering and performance measurement are possible as well. Supervision can be easily developed via proprietary devices or the integration in third party systems by means of the most common protocols as ModBus, Bacnet, Bacnet-over-IP, LonWorks. Compatibility with the remote keyboard (up to 8 units). The defrosting (air source reversible unit only) follows a proprietary self-adaptive logic, which features the monitoring of several operational parameters. This allows to reduce the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
