 WIF sizes are 16.5, 20, 32 and 40
Cubic meter.
Walk-in-Freezers are usually installed
at National, State & Regional vaccine
store.

6. WICWIC
WIC used for storage of large quantities of all UIP
vaccines like, BCG, Hepatitis B, DPT, Pentavalent,
IPV, Measles, MR and TT, except Polio.
Generator for uninterrupted power supply.
WIC comes with continuous temperature recorder
and alarm system.
Walk-in-Coolers are installed at GMSD, State ,
Regional vaccine store district vaccine store

7. Electrical CCE - WIC & WIFElectrical CCE - WIC & WIF
WICs/WIFs are equipped with following interfacing
equipment:
Temperature recorder:
Measures cold / freezer room temperature continuously on
circular chart.
Data loggers are installed with and inbuilt mini printer.
The print out from the data logger are being used for remote
temperature monitoring of WIC and WIF using internet / GSM
services.
Alarm systems:
An alarm or hooter system is provided to give alert regarding
temperature excursion / deviation.

8. Servo Controlled Voltage Stabilizer:Servo Controlled Voltage Stabilizer:

Main power is connected through a Servo Controlled Voltage
Stabilizer to safeguard the WIC/WIF from voltage fluctuations
by providing a constant voltage.
Diesel generator (DG) set:
 DG set is used to provide the standby power supply.

9. CCE- Deep FreezerCCE- Deep Freezer
Deep Freezer is an equipment, which operates on a vapour
compression system similar to any conventional type of
refrigerator operating on 220 volts, A.C. mains supply.
DF has top opening lid to prevent loss of cold air during door
opening.
Cabinet temperature is maintained between -15 C to -25 C.
⁰ ⁰

 Used for storing of OPV and preparation of IP at district level
and above only and also for freezing of ice packs at below district
level CCP

11. CCE - ILRCCE - ILR
Top opening lid to prevent loss of cold air
during door opening.
Maintain a cabinet temperature between +2 C

 Used to store vaccines at District and PHC
level.
It can keep vaccine safe with minimum 8
hours continuous electricity supply in a 24-
hour period.
ILRs are available in different sizes as under.

The larger ILR is usually supplied to district headquarters
and smaller ILR to PHC headquarters

13. ECCE - ILRECCE - ILR
How to Keep Vaccine:
All the vaccines should be kept in the basket of
the ILR.
In case basket is not available, two layers of
empty ice packs can be laid flat on the bottom of
the ILR to avoid contact with the inside floor of
the cabinet.
Vaccines should never be keep on the floor of
the ILR.
 Place a thermometer in the basket in between
the vaccines.
Freeze sensitive vaccines (DPT,TT,IPV, Penta
and HepB) at the top of the basket.

14. Heat sensitive vaccines (OPV, BCG,
Measles & JE) in the bottom of the
basket.
The vaccines should be arranged as per
their expiry dates. (Early expiry should be
above the further expiry ones).

16. Installation of ILR & DFInstallation of ILR & DF
Spacious room ( minimum size 3.5 m x 3.0
m) with good air ventilation.
The electric point should be nearest to the
place where equipment is to be installed.
There are should not be direct sun light on
the equipment.
Place the equipment in the leveled position
The equipment should be placed at least 10
cms away from the wall and other
equipment

17. Connect the voltage stabilizer for each
equipments
The electric wiring should not be less than
three core 7/20 cable of ISI marked
Three pin 15 amps socket should be ISI
marked and it should be nearest to the
equipment
No extension cord should be used
Before starting the machine check the line
for earthing and neutral

18. Installation of ILR & DF ……………Installation of ILR & DF ……………
3 pin 15 amps plug with ISI marked should
be connected with stabilizer
Connect plug with socket
Rotate the thermostat up to maximum
Switch “ON” the power supply
Allow to run the machine for 48 hours.
See the temperature become stable
Keep the thermostat at normal position
Load the ILR / DF through ice packs/vaccine
of desire quantity.

19. Hold Over TimeHold Over Time
“Hold over time” is defined as the time taken by
the equipment to raise the inside cabinet
temperature from its cut off temperature to
maximum temperature limit of its
recommended range.”
e.g. If in the case of ILR, the cut of temperature
is 4 C, then the time taken to reach 8 C from 4 C
⁰ ⁰ ⁰
will be the “Holdover time “ for that ILR.

20. Hold over time depends on the Hold over time depends on the
following factors:following factors:

 Ambient temperature
 Frequency of opening of lid and use
of basket
Quantity of vaccines kept inside with
adequate space between the
containers
 Condition of icepack lining
(Frozen/partially frozen / melted)
inside Electrical /Non electrical cold
chain equipment
Note: Deep Freezer does not have
Hold Over time like ILR
