When It’s AcuAir Clean, It’s Process Room Clean ® Cleanliness in food process rooms is paramount FRICK® AcuAir systems are precision engineered and painstakingly built to help you meet the food processing requirements of the United States Department of Agriculture. Food safety regulations seek to promote food safety through controlling: Proper and uniform room temperatures are critical for: • Beef • Chicken • Pork • Duck • Turkey Proper humidity levels are critical for: • Process room temperatures • Sanitary wash-down intervals • Condensation on room surfaces • Cleanability of equipment...

AcuAir provides temperature, pressure and humidity control for the processing environment. Managing Condensation Food contaminants generally migrate by direct contact or when attached to dirt or water particles. Airborne moisture in contact with cold surfaces increases the likelihood of condensation formation. Water droplets are highly visible and can carry thousands of microbial pathogens. Controlling the dew point of the air reduces the potential for the formation of condensation. FRICK has been in the refrigeration industry for nearly 150 years and has engineered and built environmental...

Fresh Air Fresh air in small quantities is mixed with process room air to provide positive air pressure in the space. This supplemental air offsets the air removed by processing equipment or escaping the space through doors and openings. Providing makeup air effectively controls the infiltration of unconditioned air into the process room. Pre-Filter The mixed air is immediately filtered to capture airborne particles that could compromise the integrity of the hygienic process air unit. In addition to enhancing internal cleanliness, these filters economically extend the service life of the...

The AcuAir solution is about continuously flushing the space with dry, clean air and exhausting saturated, dirty air. 100% fresh outside air is drawn into the AcuAir hygienic unit. The fresh air is conditioned for optimal moisture collection and filtered to hygienic quality. The dry, clean air sweeps across the ceilings and walls as it is delivered to the space undergoing cleanup. This dynamic flow of air dries the surfaces it encounters, capturing suspended moisture and drawing it toward the return air opening. Once in the return duct, moisture-laden air is exhausted to the outdoors....

Carbon Dioxide (CO2) Abatement Units Carbon dioxide exposure is limited by federal regulation. CO2 concentrations are not allowed to exceed 5,000 PPM for continuous occupancy. Receiving and storage areas containing product packed in CO2 pellets will accumulate high levels of airborne CO2 gas. AcuAir CO2 abatement units use dual airstreams to efficiently remove the high concentration of CO2 from the space and replace with conditioned fresh air. Utilizing energy recovery, the conditioned CO2 airstream is used to temper the incoming fresh air, thus reducing the cooling load required to...

Heating Options Typical clean-up heat is direct fired gas heater with a high turndown ratio for accurate temperature control. Other options include: indirect gas heat, steam, etc. [i) Fresh-Air Plenum Inlet plenum and hoods block out rain and snow, and are constructed of a single wall of sheet metal. Materials used in fabrication are selected to match the unit's exterior. Refrigerant Detector Refrigerant-cooled units are equipped with a chemical cell refrigerant gas detector that is connected with the AcuAir controller. Smoke Detector A smoke detector is provided as standard on every unit....

Mixing Box The mixing box is the merge point of the return and the fresh makeup airstreams. Low air velocity prevents water carryover and provides uniform flow into the pre-filters. Controls Standard AcuAir Quantum™ HD computer-based controls are factory-wired to the unit starter/ disconnect and VFD panel. A NEMA 4X remote mode selection panel and optional operator interface touchscreen panel are shipped separately. The AcuAir Quantum™ HD controller comes standard with Ethernet communications capability. Optional AcuAir A-B controls are also available. Fresh- and Return-Air Dampers AcuAir...

Optional Features Gas Heat in Production Some process rooms require additional heat during production mode operation. That happens when the cooling effect of the makeup pressurizing air is greater than the heat load being generated in the space. AcuAir has the ability to apply several technologies to provide and control heat in the process mode. Sequential Defrost Where process room operating temperatures must be low, the likelihood of frost building up on the cooling coil increases. AcuAir has technology that allows the hygienic unit to operate in that frosted cooling coil condition, and...

Parallel Fan Assemblies Operation of the AcuAir hygienic unit is critical for keeping the process room in production. AcuAir offers the option of parallel plenum fans to provide a degree of redundancy in the event of mechanical failure and to reduce the size of individual fans and motors. Should a fan or motor fail, the remaining fans will continue to operate, providing sufficient air flow to the room and preventing a shutdown of your process space. Motor Service Rails Changing out heavy fan motors inside tight spaces can be both stressful and hazardous, especially under time constraints....
