The Heat Driven Loop (HDL) uses the energy release of steam created by the patented two phase thermo-siphon and heat driven loop technology delivering a cost effective, reliable and safe process fluid heating system.

The HDL is a high efficiency, low exhaust emission, indirect fired heating system.

It is multi-fuel capable for all domestic and industrial applications.

The HDL incorporates millivolt technology for operator-friendly fuel train and temperature controls.
This technology is easily retrofitted to existing firetube throats for single or multi-tank or vessel configurations.

The HDL is an engineered and field-proven product in reducing overall production heating costs.
