CWT Indirect Line Heaters

CWT Natural Gas Dry Line Heaters lead the pack in environmental responsibility and economic viability.

Based on Tecvalco Ltd.’s patented Heat Driven Loop technology, CWT heaters provide true indirect heat that results in tremendous thermal efficiencies.

CWT Natural Gas Dry Line Heaters are a revolutionary approach of using low pressure and low temperature steam to more quickly, more economically and with less greenhouse gas emissions to heat natural gas at town border stations or other facilities. Millivolt controls are supplied by power from thermopiles installed by a standing pilot meaning no power or generators need to be installed on location. The low volume of glycol, the system operating under a vacuum, and the familiar off-the shelf safety and fuel supply components lead to ease of use, inspection and repair.

The Heat Driven Loop technology has found uses in other applications as well, such as our tank heating system and mechanical treaters.

Please note, in order to size your heater correctly, we require the following:

  • Station in pressure
  • Station out pressure
  • Station in temperature
  • Station out temperature
  • Typical flow rate
  • Maximum flow rate

The CWT features vastly increased THERMAL EFFICIENCY over traditional line heaters. As opposed to COMBUSTION EFFICIENCY, which is solely an indicator of how effectively a burner consumes fuel, THERMAL EFFICIENCY is a ratio of the heat transferred to process, compared to the overall energy present in the fuel. A heater can have high combustion efficiency, but still have a low overall thermal efficiency if the transfer process is ineffective.

When comparing the CWT to other heating solutions, be sure to check not only combustion, but overall thermal efficiency.
