Overview

The Rentech D Type Watertube boiler is known for its proven reliability, which is due, in part, to the 100% membrane wall construction eliminating the need for refractory and assists in reducing emissions. Efficient heat transfers enables the Rentech D Type Watertube to achieve full steaming capacity more quickly than with designs used in other boilers.

This watertube boiler was purchased new through another boiler company that works closely with Powerhouse. This unit has been kept in a climate-controlled Powerhouse warehouse since purchase and is ready for full time steam duty.
