When the first words anyone reads when they visit your websites homepage is “Helping Leaders Create Better Working Environments For Hard-Working People” it would be a good idea to practice that within you own facility as well……just saying.

Here at Cambridge Air Solutions we have always practiced what we preach throughout the cold winter months through the use of industry leading High Temperature Heating and Ventilation (HTHV) heating technology. Through the use of HTHV units we have the ability to keep our facility comfortable warm where the hard working people are…..down on the factory floor. Along with our commitment to utilizing energy efficient HTHV technology to reduce our carbon footprint we have also installed solar panels on a major portion of our roof to help further reduce our carbon footprint and generate electricity on those bright sunny days.

But there was still that last piece of the puzzle, and just as important as comfortably heating a facility in the winter, which was to find a way to cool our facility during the hot and humid Saint Louis summer months. A better working environment is comfortable year round, not just when the temperature dips below freezing. The biggest hurdle in cooling our facility is not the lack of technology but the acquisition and operating costs of different technologies that are available. Even with the electricity that our solar panels generate a DX mechanical cooling solution for our facility would be too costly to operate. Instead we have chosen to use a two stage evaporative solution to provide a more comfortable indoor environment for our Cambridge family members who work on the factory floor that uses less electricity and continues to reduce our carbon footprint.

To follow our journey as we work hard to provide a better working environment during the summer months as well, follow us of Facebook - https://www.facebook.com/cambridgeengineering/  - as we will post updates throughout the journey.

We applaud any leader's commitment to an improved work environment for their employees, and recognize the huge investment that this commitment can take. Since the heating, cooling and air quality of a building can play such a major factor in a happy and productive environment, we wanted to provide you with some simple mid-year maintenance tips to make sure your commercial and industrial HVAC systems are in check.  Below you can find some recommendations from Ryan King and Mike Bess, members of the Cambridge customer service team.

  1. Check the air filters.  Clean these filters if necessary because dirty filters will reduce CFM and could damage the discharge air sensor. 
  2. Grease the bearings.  The grease should be evenly distributed around the race; however, do not use the standard bearing grease in the Baldor motor.  This motor takes special grease that can be referred to in the technical manual.
  3. Check the belt tension and inspect for wear.  If the belt is too tight, it can  prematurely wear out the bearings and the belt.  If the belt is too loose it can slip or squeal.  
  4. Cycle the unit on and off in all modes of operation.  This ensures things are working per specifications.
  5. Check the discharge temperature.  Use a wired thermistor at the mixing box and calibrate the system if necessary.
  6. Inspect the control panels.  Look for any loose or frayed wire connections and make sure all connections are tight.  
  7. Check and clean the evaporator and condenser coils.  Dirty coils will drastically reduce cooling equipment efficiency and strain the compressor. 
  8. Perform a gas valve leak test.  This verifies the integrity of the valves.
  9. Verify that the manifold differential gas pressure matches the nameplate.  It is extremely important that this is set up properly.  If the manifold pressure is incorrect, the heater temp rises and its efficiency will be affected.  
  10. Inspect direct evaporative media (CELdek).  Ensure that there is proper water flow across the media. 
  11. Check the calibration of digital thermostats.  Press the up arrow and hold it; the display should show 0F.  If not, the calibration may have been adjusted to show a warmer or cooler temperature than desired.

We know you’re busy, and sometimes the easiest way to get direction on a service question or instructions on how to install can best be obtained by a quick “How-To” video. For that reason, we’ve compiled some service videos that you can view at your convenience that may help you with a Start Up or troubleshoot a problem you may be experiencing.

As always, our service team is happy to assist you with any questions you may have. Please call us at (888) 976-4451or email: service_dept@cambridge-eng.com
