The Distributed Energy Solutions Division (DES) of Stewart and Stevenson Services Inc. (Houston, TX) introduced a new family of EnGen-Therm™ power modules. The EnGen-Therm power module is a natural-gas-reciprocating engine generator that is designed for easy integration of a heat recovery unit (HRU) or absorption chiller system. The engine generator provides enough heat from its exhaust and water jacket to produce hot water or steam using an HRU. The new family of EnGen-Therm modules is designed to produce a balance of power and cooling, hot water or steam, to meet the needs of small-size to medium-size commercial, institutional and industrial customers.
The EnGen-Therm models deliver continuous power output ranges of 280kW, 375kW, 560kW or 750kW along with thermal output of 1,700MBtu, 2,277MBtu, 3,352MBtu or 4,511MBtu per hour. Water jacket and exhaust temperatures are approximately 210°F and 1,115°F, respectively. The unit can be remotely operated and monitored and is designed to provide maximum uptime. The EnGen-Therm system will offer standard specifications as well as optional features to fit customer-specific applications.
Stewart and Stevenson's DES team is currently building and installing a number of the units for hospitals, office buildings and small-process industries in the US that have a demand for both power and heat. DES will provide a value chain of distributed generation support services for the new product rollout. Services will include installation, operation, maintenance, parts and financing.
