* Measured with high accuracy data-logger at sample storage area with standard Set Point.

* Custom built Chambers are available in any dimensions and capacities.

Standard Chamber Features & Provisions:

  • Construction: PCGI/SS304/SS316 Tongue & Groove Type Panels with PUF density of 40Kg/m3-Thickness: 120 mm for Deep Freezer

            With Pre-cooling Chamber (Ante-Room): Panel Thickness 80 mm

  • Sample Storage:
  1. Racks: Heavy Duty SS304 Frame secured strongly to chamber walls for strength.
  2. Trays: Perforated types (CNC punched). Strengthened with support rails to prevent deformations.
  • Door 1: For Ante Chamber: PUF Insulated door with Viewing window of Double Layered Toughened Glass, mounted with imported hinges & locks.
  • Door 2: For Deep Freezer: PUF Insulated door mounted with imported hinges & locks.
  • Door Operation: Passcode protected door - from software & HMI.
  • Control System:
  1. Ergonomically designed control panel.
  2. Ferrule printed wiring.
  3. Advanced PLC Program with built in processor-based Auto Tuning.
  4. 2 Separate 4.3” HMI Color LED Display. (For both: Ante Room & Deep Freezer)
  5. Built in Redundancy & Safety.
  6. Advanced High Accuracy “Transmitter Sensors” with output of 4-20 mA.
  • Temperature Control:
  1. Efficient, Reliable, Time tested & Trustworthy Refrigeration Design. Frost Free with De-frosting system.
  2. Built in redundancy with PLC based Auto Change Over during power outage &/or component failure


  • PLC Safety Cut Off for Temperature: Low, Lower & High safety cut off.
  • Human Safety: “Person Trap” button provided inside the Ante chamber, which triggers Audio Visual alarm. The button enables the trapped person to come out even if the door is physically locked from outside
  • Emergency Stop: Button provided from outside.



Walk In Deep Freezers:

The Pharmaceutical & allied industries use Deep freezers for effective storage of drug products, life-saving vaccines and samples for diagnosis, but are also perfectly suited for temperature tests and aging subjected at sub-zero temperatures.

They can be used for storage of fresh and frozen blood supplies and vaccines, also for storage of enzymes for research.

Allyone Walk-In Deep freezers are available with "Ante Chamber" as a barrier between Ambient & Sub Zero, so as to cool down the samples from ambient temp to near zero, then shift them in the Deep Freezer so as to make the process more efficient & economical for your need for a precision-controlled storage equipment as low as -30°C. Allyone deep freezers have great safety features and are trustworthy & reliable.
