turnkey industrial water heating systems

Custom Thermal Applications’ turnkey industrial water heating systems provide an opportunity for energy savings and emissions reduction. The QuikWater Direct Contact Water Heater is the flagship of our water heating systems and will be especially attractive to a client needing large volumes of hot water.

Heating the water by passing it directly through the combustion gases, QuikWater provides:

  • Improved water quality.
  • Food Approved – potable water in means potable water out.
  • 99% thermal efficiency with corresponding low emissions levels and fast payback from fuel savings.
  • Speed – single pass, on-demand heating at rates from 5 GPM to 2300 GPM (for standard, single tower units. Higher flow rates with multiple tower units.)
  • Water temperatures up to 200ºF (93ºC) in a single pass from supply water as low as 32ºF (0ºC).
  • Eliminates the need for hot water storage tanks (although they may be used if desired).
  • Consistent output water temperature even during fluctuating or peak demands.
  • Reliability demanded by large industrial users.
  • Low maintenance costs and long service life (stainless steel construction and the absence of boiler tubes).
  • Qualifies for rebates provided by the gas companies to clients who install high efficient gas burning equipment.
  • Low NOx packages available – under 30 PPM, under 20 PPM, and under 12 PPM.

Conventional Boilers: Conventional hot water or steam boilers will be needed for many plant process requirements. As a combustion services firm, we are able to source most makes of boilers and recommend a “best fit” solution. With our in-house engineering, we can size and supply the boiler, specify and supply the piping and ancillary equipment needed for a successful application, and design and supply a control panel (if needed) to integrate the package with the client’s plant.

Accessory Packages: We design and supply high and low-pressure pump skids and hot water storage systems as may be needed to compliment the client’s new water heating package. Package options include pumps, motors, drives, tanks with temperature and level controls, pump speed or other discharge pressure control options plus a custom designed panel to provide these controls and integrate the new accessory pump package with the new water heater or other parts of the clients existing plant.

We also supply heat exchanger packages for heating liquids other than water.

In-House Engineering: Custom Thermal provides engineering assistance for application design to clients considering new or upgraded water heating systems.

Installation: Complete turnkey installation, start-up and testing of our water heating packages are provided by Protherm, our affiliate service company.
