The HQC45 QuickChiller is designed for rapid chilling of 45 pounds of food (9 pounds of food per pan
in five 12" x 20" x 21⁄2" pans or five 18" x 26" sheet pans) from 150°F to 37°F in approximately 90 minutes.
The rapid chilling process preserves food quality, texture and nutritional value for up to 5 days. As
many as 5 chill cycles can be handled per 8 hour shift. At the end of a chill cycle, the chiller
automatically goes into Hold mode at normal refrigerator temperatures, enabling overnight chilling.
The HQCF45 QuickChiller-Freezer is designed to chill exactly like the HQC45 and it can also freeze
product down to – 20°F. Freezing time varies according to the initial and final product temperatures
as well as product type and quantity. Coated wire shelves can accommodate five full-size 12" x 20"

LOCATION
Good air circulation at the condenser coil in the lower section is necessary to provide proper operation.
The cabinet may be located in any one of the following three ways to assure satisfactory performance.
• The unit can be situated so the lower back section is open to room air, allowing free air discharge.
No side clearance and no top clearance is required. This is the preferred situation and provides
the most effective cooling.
• The unit can be provided with no side clearance, two inches of clearance at the rear, and six inches
of clearance above.
• If the unit is situated with no back clearance and no top clearance, it is necessary to provide either
five inches of clearance on each side or ten inches of clearance on one side of the cabinet.
NOTE: Performance is enhanced when the air going into the condenser coil through the lower front
section is cool. For example, locating the chiller adjacent to an oven would not be recommended.
FEATURES
Shelves (Set of Five)
A set of five shelves is optional on HQC90. A set of five shelves is standard with HQC45 and HQCF45.
