Green Refrigeration: Cool Vap Evaporator Coils

Cool Vap Evaproator Coil

Reihl Efficient LLC has a great new Green Refrigeration product on the market. The Cool Vap Evaporator Coil for Walk In Coolers is a major advance in Commercial Refrigeration technology.

I recently went on a tour of the Reihl Efficient factory in Michigan. The folks at Reihl Efficient have figured out how to maintain & even decrease the box temperature of Walk In Coolers during the compressor off cycle. This has huge energy saving potential. Cool Vap coils in my opinion are a breakthrough in Green Refrigeration! I was very impressed by the facility & the high quality of the Cool Vap evaporator coil assemblies. All models come standard with high efficiency electronically commutated evaporator motors.  The panels & coil housing are several times thicker than other coil brands & the coil should be more durable due to it’s configuration.

Mike Reihl has come up with a fantastic idea on how to tap into thermal inertia during a refrigeration off cycle to maintain & even lower box temperature. Cool Vap coils have a custom built chamber that rests on top of the evaporator coil. This chamber is filled with a proprietary mass. This mass builds & stores cold energy during the compressor run cycle. During the refrigeration off cycle this cold energy can be released back into the box by cycling the evaporator fan while leaving the compressor off! The Walk In Cooler is able to maintain or drop temperature without running the compressor. Cool Vap Coils take Green Refrigeration to the next level! Independent studies have been conducted. One showed an electrical savings of 37% & the other showed savings of 72%! Cool Vap Energy Efficiency study, coil sizes & specifications available on manufacturers website.

The manufacturer is so confident in the performance of their Cool Vap coil that they are offering a Performance Guarantee Agreement! They guarantee at least a 35% reduction in the electrical expense associated with running a walk in cooler or they will compensate the difference for the equivalence of two years!

Cool Vap coils come standard with 1 or 2 EC (electronically commutated) high efficiency evaporator motors. The coils range in size from 7,000 – 17,000 BTU’s.

KE2 Temp + Defrost Controller Is Innovation In Refrigeration

The KE2 Temp + Defrost Controller represents a major advance in Commercial Refrigeration temperature & operation control. Never before has temperature control, automatic defrost & anti short cycling been combined into one digital controller.


KE2 Temp + Defrost Controller For Medium & Low Temperature Reach In & Walk In CoolersWe are excited about the introduction of the KE2 Temp + Defrost Controller to the Commercial Refrigeration market recently. This product offers many new features for the control of medium & low temperature refrigeration systems that had previously required separate components for individual functions.

In the past temperature control, defrost & anti short cycling could be achieved only by using one component for each function. A thermostat was needed for temperature control, a separate defrost clock for defrost & a relay for anti short cycling of compressor. Now the KE2 Temp + Defrost Controller can handle all three tasks on medium temperature Refrigeration Equipment (low temperature applications would still require a separate defrost circuit for evaporator fan & coil heater control). The old style temperature, defrost & anti short cycle controls were usually mechanical. All of these features (temperature control, defrost & anti short cycling) are digital & included within the new Ke2 control.

We know from in the field experience that digital controls offer far better precision & accuracy than comparable mechanical refrigeration controls. KE2 also offers a visual alert for high temperature, low temperature & sensor. The control also indicates when system is in defrost mode & also when system is recovering temperature from a defrost mode. This feature cuts down on false alarms & unnecessary service calls. Ke2 is dual voltage & can operate on either 120 or 208 – 240 volt power supply. We believe that this new product offers great features in one digital control. We will be using the KE2 Temp + Defrost on most refrigeration repair & installation jobs in the future due to it’s features & dependability.

Features of the KE2 Temp & Defrost Controller:

  • Thermostat
  • Off time defrost on schedule or custom defrost
  • Compressor protection – Maximum starts per hour
  • Manual defrost
  • 1st defrost 2 hours after start up
  • Visual alarmingHigh temperature / Low Temperature / Sensor
  • Space temperature sensor is supplied with 10 foot lead


  • Relay for solenoid / compressor
  • 3 digit 7 – segment display
  • 4- button user interface
  • Modbus terminals (KE2 Temp includes RS-485 Modbus Communication)

Mitch Byrne Is A Refrigeration Repair Expert

Mitch Byrne is a refrigeration repair expert. He has worked within the HVAC & Refrigeration trades for over fifteen years. He has concentrated on the diagnosis & repair of Commercial Refrigeration & Ice Machines in the Chicago area.

Mitch started his career as an unskilled laborer working in boiler demolition. He spent his days lugging bricks & large heavy boiler sections out of basements for minimal pay. After less than a year doing this back breaking & unrewarding work Mitch decided to enroll in HVAC & Refrigeration College to further his education & get a better job in the trades. He attended Coyne College in 1997 & graduated at the top of his class with full honors.

After attending trade school Mitch worked at a few residential heating & air conditioning companies in the North & West suburbs. While at the two companies he learned about installing heating & air conditioning systems including SpacePak. Mitch decided residential work was not for him & moved on to several  different Commercial Refrigeration & HVAC outfits.

Mitch learned very quickly & found his strength was in Commercial Refrigeration service & repair. Between 1998 & 2007 he worked at several HVAC & Refrigeration shops. While working at various shops he learned about HVAC, cooking equipment & refrigeration equipment.  He moved up at a rapid rate everywhere he worked due to his excellent diagnostic & repair skills as well as his communication skills related to dealing with customers. In 2007 Mitch hit the top of the pay scale available at that time. It was then that he decided to start his own business specializing in Commercial Refrigeration Service & Repair in Chicago land. Northeast Cooling LLC was founded in 2007 & has been going strong ever since then. Mitch Byrne Is A Refrigeration Repair Expert.

Chicago Is A Great Place To Do Refrigeration Work

There are literally dozens of reasons why Chicago is a great place to do refrigeration work. There are thousands upon thousands of potential customers including all the bars, restaurants, hotels & schools throughout the area. One of the best reasons to work in the refrigeration trade is all the beautiful views we get to catch from roof tops across the city!

Chicago Sunrise From Humboldt Park

Recently Mitch Byrne of Northeast Cooling was honored to be quoted in a blog post & press release done by Emerson Climate Technologies. The post was titled “The Top 10 States to Work in HVACR”. According to the blog Illinois ranked number five. It was beaten by California, Ohio, Florida & Texas. California, Florida & Texas we can understand due to all the excessive heat. While these states “may” have beaten Illinois in Emersons post we believe Illinois is a much better state to work in! We believe Illinois provides a superior advantage when it comes to a potential customer base & great networking opportunities. When you consider all Chicago has to offer like thousands of businesses in need of refrigeration & HVAC we find it hard to believe there is a better state to work the trade in!

Chicago has some extreme & unpredictable weather. We go from Blazing hot Summers to sub-zero windy & icy Winters. All these weather changes are tough on commercial refrigeration equipment. Remote or outdoor compressor units have the hardest time dealing with all these temperature fluctuations. Peak season weather is hardest on these units. That includes the hottest AND coldest days of the year. Believe it or not, some of our busiest days are when the temperature dips below zero degrees. This causes all sorts of low ambient problems for outdoor refrigeration compressor units. We have done whole blogs on this very topic. Here is more information on how cold weather affects outdoor refrigeration units. The bottom line is that between the great views, temperature swings, REAL seasons & phenomenal customer base we truly believe that Illinois is the best state to work in HVAC & Refrigeration!
