Langley Memorial Hospital is a government-funded acute care facility in the Township of Langley British Columbia that is owned and operated by Fraser Health Authority.
Mark Gushulak, Chief Engineer at Langley Memorial Hospital had a Hot Water Tank that had been operating successfully since the mid 1960’s providing years of trouble free service. Inspection revealed cracks starting in the shell and a project was initiated to replace the tank. A call was made to Andrew Reynolds to supply an Instantaneous Domestic Hot Water Heater capable of handling the same flow. A turn-key quote was provided that involved removal of the old tank, reconstruction of the tank mezzanine level and installation and commissioning of the new hot water heater. Included in the design was a steam powered condensate pump that returns the condensate back to the boiler.
This successful solution has been in operation for many years now and is once again providing Langley Memorial Hospital trouble free domestic hot water service. Mark Gushulak reports we are very pleased with the installation and there may be an opportunity in the future for another instantaneous domestic hot water heater.

Deaerators in Industrial Steam Systems
Deaerators are mechanical devices that remove dissolved gases from boiler feedwater. Deaeration protects the steam system from the effects of corrosive gases. A dissolved oxygen level of 5 parts per billion (ppb) or lower is needed to prevent corrosion in most high-pressure (>200 psi) boilers. While oxygen concentrations of up to 43 ppb may be tolerated in low-pressure boilers, equipment life is extended at little or no cost by limiting the oxygen concentration to 5 ppb. Dissolved carbon dioxide is essentially completely removed by the deaerator.
