Sea Water Source Heat Pump

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

• Significantly saving energy costs associated with heating and cooling of the water tank at eel farms and aquaculture farms
• Maintaining the optimum temperature by accurate temperature control for the growth of the young and live fishes
• Extended equipment life and easy maintenance with the titanium dual pipe and spiral tube heat exchanger
• 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
• 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.
