REDUCE THE COST OF YOUR PROCESS
Ovens, dryers, sterilization processes, cleaning in place, cooling... Industry consumes 310 TWh per year -- 20% of fuel consumption in France -- of energy and dissipates up to 60% of this heat in its effluents.
EHTech designs custom-made systems to recover lost heat from polluted wastewater so that you can optimize the cost of your process.

EVEN ON LOW TEMPERATURE WASTEWATER
Obox I heat recovery units capture heat from effluents between 20 and 40°C.
More than 50% of the waste industrial heat is dissipated by effluents at less than 100°C. EHTech's expertise is precisely in the capture of fatal heat from effluents between 20°C and 40°C,
This resource is often left aside because it is difficult to develop, wrongly because it represents a large part of the fatal industrial heat.
Obox I, with its low-temperature capture, allows you to collect this energy.

EVEN ON VERY POLLUTED WASTEWATER
EHTech's technology is focused on maintaining recovery efficiency even when the effluent is very polluted.
EHTech's 7 patents all directly answer the question "how to maintain initial thermal performance when wastewater is highly polluted?". The self-cleaning system that the EHTech team has developed requires only a minimum number of parts.
Since 2009, EHTech's recovery systems have captured the heat of wastewater loaded with all kinds of pollutants: hair, sand, grease and surfactant suspensions.... These recuperators can be adapted to treat salty, chlorinated, acidic or alkaline effluents.

NO HEAT PUMP
EHTech designs robust systems, without phase change, with a minimum of moving components.
For EHTech, robustness is more critical than thermal performance. You do not want to weaken your process and to achieve this 99.9% service, the Obox I systems operate without a heat pump.
To facilitate preventive maintenance, all parts of the Obox I systems can be dismantled.
