NAKS's Compliance Why You Should Care
Doors Doors must have automatic door closers that close the door fully within 1" of the closed position required for all doors, except those wider than 3'9" or taller than 7'0". All NAKS Walk-In doors come standard with a Kason Automatic Hydraulic Door Closer. An Automatic Door Closer is a great ‘Green Initiative’ component because it minimizes the risk of the Walk-In door being left ajar. An open Walk-In door causes a high energy consumption to keep the Walk-In at the appropriate temperature. Just as importantly, it will protect the goods inside by preventing an extended period of outside air infiltrating the box from an open door.
Strip doors, spring hinges, or other methods of minimizing air infiltration are required when doors are opened. All NAKS Walk-In doors come standard with Kason Spring-Loaded Hinges. Spring-Loaded Hinges mechanically close the door once opened. Like the Hydraulic Door Closer, it prevents an extended period of outside air infiltrating the box from an open door.
Insulation Wall, ceiling, and door insulation must be at least R-25 for coolers and R-32 for freezers. All NAKS wall, ceiling, and door panels meet or exceed all minimum requirements for R-Values (and K-Values). Our standard panels are industry-leading 4” thick for Coolers & Freezers Thicker panels, and efficient insulation make the temperature inside the walk-In easier to maintain. The panel limits the outside air infiltration into the box, lowering energy consumption and reducing operating costs. It also maintains your product inside the walk-In at a more constant temperature.
Floor insulation must be at least R-28 for freezers. NAKS standard floor panels meet and exceed all minimum requirements for R-Values, and are industry-leading 4” for Coolers & Freezers Our floors have the same resistance to heat as the rest of the Walk-In panels. Therefore, it greatly reduces the amount of outside air that infiltrates the Walk-In via the floor.
Motors Evaporator fan motors of less than one horsepower and less than 460 volts are required to be electronically commutated (ECM) motors, or 3-phase motors. In all applicable Walk-Ins, NAKS’s standard refrigeration unit is a Heatcraft Climate Control evaporator fan motor with ECM motors. (voltage restrictions may apply) These specific features of an Evaporate Fan are built to protect the environment by reducing overall energy consumption, thus reducing operating costs as well.
Condenser fan motors of less than one horsepower are required to be electronically commutated (ECM), permanent split capacitor (PSC), or 3-phase motors. All NAKS condensing units provided by Heatcraft meet or exceed all DOE requirements. These specific features of a Condenser Fan are built to protect the environment by reducing overall energy consumption, thus reducing operating costs as well.
Lighting For all interior lights, use light sources with an efficiency of 40 lumens per watt or more, including ballast losses (if any), except that light sources with an efficiency of 40 lumens per watt or less, including ballast losses (if any), may be used in conjunction with a timer that turns off the lights within 15 minutes, when the walk-in is not occupied. All NAKS standard lighting options are two to three times greater than the lumens per watt requirement. Lumens per watt is essentially the brightness output compared to the amount of energy consumption. A higher number of lumens per watt means the brighter the light will be per unit of energy consumed.
Other Initiatives EPA requirement NAKS’s panel insulation is class 1, rigid XPS Extruded Polystyrene, non-CFC. CFCs, or chlorofluorocarbons, are harmful to the environment by damaging the ozone. Non-CFC Polystyrene is required by EPA initiative.
