* Product Overview
An eco-friendly heat pump system that recovers sensible heat from the sea water and supply the recovered heat to the heat/cool the water tank, or produce cold/hot water without using any fossil fuel thereby saving energy and reducing greenhouse gas
* Features
① Significantly saving energy costs associated with heating and cooling of the water tank at eel farms and aquaculture farms
② Maintaining the optimum temperature by accurate temperature control for the growth of the young and live fishes
③ Extended equipment life and easy maintenance with the titanium dual pipe and spiral tube heat exchanger
④ Fitted with the aerification system to the heat source tank so as to generate air bubbles to remove sludge and optimize the heat transfer of the evaporator
⑤ Ability to recover heat even from the low temperature heat source (up to 5°C)
* Application
Applicable to any sector that uses sea water as a heat source and requires hot water and heating/air-conditioning such as Land aquaculture, Mariculture, Offices near the sea shore, Commercial buildings, Motel, Sauna and so on
* Specification of Sea Water Source Heat Pump (IWS-55A, 53A, 13A Series)
