AIRFLOW & DEFROST

AIRFLOW & PRODUCT LOAD

H

illphoenix cases provide maximum product capacity within the 

refrigerated air envelope.  Please keep products within the ap-
propriate load limit.

It is important that you do not overload the food product display 
so  that  it 

impinges  on  the  airfl ow  pattern  (Fig.  8).    Overload-

ing will cause malfunction and the loss of proper temperature 
levels, particularly when discharge and return air sections are 
covered.

DEFROST & TEMPERATURE CONTROLS

Cases are equipped with either Electric, Hot Gas, or Timed-Off 
defrost at the owner's option.  

The  hot  gas  defrost  termination  sensor  bulb  and  probe  are 
attached to the dump line which is in the front, left-hand side 
of the case.  

     

W A R N I N G

Always keep product within the designated  air 
curtain.  Failure to do so may result in case 
malfunction and product losing proper tempera-
ture, resulting in sub-standard operation and 
increased chances of food contamination.

HUMIDIFICATION SYSTEMS

The starting point for proper humidity levels in the AGB display 
case are typically around 75% RH when stocked with product.  
The  RH  will  vary  during  defrost  or  cycling.    A  humidification 
system is recommended to ensure consistent performance in 
all store ambient.  Several factors  to consider are listed below 
and adjustments may need to be made to the setting for par-
ticular configurations to maintain humidity levels within a case.

1.  Store Conditions - 

Hillphoenix cases are designed to oper-

ate  in  an  air-conditioned  store  that  maintains  a  75°F 
(24°C) store temperature and 55% (max) relative humidity 
(ASHRAE  conditions).    Case  operation  will  be  adversely 
affected by exposure to excessively high ambient tempera-
tures and/or humidity.

2.  Desired  Case  Temperature  - 

Hillphoenix  recommends  a 

set point of 33˚-36˚F.  If the meat is too cold the meat may 
freeze and the aging process will slow or stop.  If the meat 
is too warm it will spoil.

3.  Dry  Aging  Process  - 

Dry  aged  beef  is  typically  stored  for 

14-21 days in a humidity and temperature controlled envir-
norment. The productmoisture content, desired shrink and 
approximate timespent in the aging process all are factors 
related to the amountof humidity the product releases into 
the case environment.

All set points and parameters are starting point and 
must be adjusted to meet ambient conditions and 
desired product temperatures.
If store conditions are very dry, an optional humidification sys-
tem is recommended.

If your case is equipped with a Dixell temperature and humidity 
controller, see Appendices B1-B4 for operating instructions. 

DETERMINING SUPERHEAT

To identify proper superheat settings, complete the following:

1.  Obtain  suction  pressure  from  access  port;  obtain  suction 

line temperature from area near TXV bulb at the outlet of 
evaporator coil.  

2.  Using  the  suction  pressure  reading,  convert  pressure  to 

temperature  using  temperature  pressure  chart  (

see 

Appendix C1

).  

3.  Finally,  subtract  the  converted  temperature  reading  from 

the actual temperature reading for superheat setting.
