Heat Waste to Heat (W2H)
- The heat is transferred to other areas of the facility for other processes or energy reduction.
- The heat may be transferred through alternative fluids e.g air to water, water to glycol etc best suited to the process.
- Waste heat to other heating application scan be transferred with very little loss.
HEAT W2H
HEAT W2H (Heat Pumps)
gTET can design and install high efficiency, high temperature heat pumps providing up to 120°C hot water resulting in significant energy and emissions reductions compared to gas boilers. The heat pumps can be coupled with chiller condensers or other forms of waste heat to further reduce energy consumption
