AC19

John, Ashley, James and Brad,

Thanks for your time today and it was a good discussion. We are a growing company and are controlling 

thousands of the existing low amperage doors the OEM’s are using to meet the current standard. 

In today’s call we discussed the new CRE proposed standard and how ControlTec anti-sweat controls can 

help meet those standards without sacrificing equipment performance or integrity. We have a 

revolutionary product that is the only in the business that has built in Measurement & Verification 

(M&V). All other anti-sweat heater controls are old technology that has algorithm’s to estimate store 

conditions inaccurately. 

Points of discussion:

1. DoE has no anti-sweat heater requirement.

2. Manufacturers are using decreased door heat to meet the existing 2009 standard.

3. Weighted average reduction for new proposed standard is 15%.

4. Other improvements include more insulation, better glass and coatings, and compressors.

5. New standard only requires and tests for daily kWh consumption.

6. The current ASHRAE testing standard adopted by the DoE is for CRE equipment at 55/75.

7. Decreased door amperage/heat is creating issues across the country for retailers and 

customers. 

Brad Geuke is included in this email and please send us the new proposed standard.

Thanks again,

Mark Hanson

Ali Nouri,

Thank you for your time on Friday and here is the requested synopsis. 

ControlTec LLC designs, manufactures, and markets anti-sweat controls for

the refrigeration installed in grocery/convenience stores nationwide. We 

have developed the ability to control significant energy use in the pieces

of equipment while maintaining the sustainability. As a company, we would 

like to see if such controls are being considered in the Proposed Rule and 

understand the time frame for public comment is short. 

Our concern is that the anti-sweat heaters implemented by manufacturers to

meet the new standards will not perform for many areas of our country that 

experience higher humidity levels during the summer months. This will lead 

to condensation on the frame and glass of transparent doors and reduce the 

life of such equipment. The current standards require such low levels of 

heat that in over one-half of the country, the doors sweat and lead to 

problems in the retail environment for months. We work with 

customers/refrigeration companies nationwide and can have many signatures to

a petition stating so.

Our solution is to allow the necessary heat in the equipment and use our 

controls to turn off that heat when not needed in low dew point conditions. 

This allows the equipment to operate as designed, extends the life cycle,

and saves significant energy annually without all the problems. 

In short, we would like to have a contact at the DOE to meet with and 

discuss our concerns and strategy. 

I am attaching a brochure for equipment specifications and look forward to

hearing from you, 

Mark Hanson
