Engine
TOTEM internal combustion engines are specifically designed to run on natural gas. They are controlled with automotive engine control units with high efficiency catalytic converters which give ultra low NOX and CO emissions under 10 mg/Nm3.
The TOTEM delivers the lowest emissions available from any reciprocating engine CHP, and lower NOX emissions than a condensing gas boiler.
High Efficiency Heat Exchange
Maximum thermal efficiency is achieved by reclaiming heat from every available source. The building's central heating water is heated directly in two stainless steel shell and tube heat exchangers and a water to water stainless steel plate heat exchanger to transfer heat from the engine coolant system.
The engine coolant system is used to cool the engine, oil, and generator water jacket. This level of heat exchange gives the TOTEM a thermal efficiency of 65% or higher depending on the return water temperature.
The TOTEM will condensate when the return temperature is less than 50°C, without the need for an additional flue heat exchanger.
Advanced Controls
Advanced ControlsAn innovative cloud platform is standard to TOTEM, designed for Smart Buildings and allows remote monitoring of TOTEM performance by any system online (laptop, tablet, or smartphone). The TOTEM can provide this functionality through either a hard wire network connection or via a WiFi module installed in the unit.
The remote monitoring system can be interrogated for real time information, or set to upload a packet of data every 24 hours detailing the unit performance over the past day. Faults can automatically create email alerts.
The TOTEM delivers the lowest emissions available from any reciprocating engine CHP, and lower NOX emissions than a condensing gas boiler.
