DUAL-FREEZER high speed freezer doors provide superior temperature control, energy efficiency and enhanced traffic flow.
With the innovative double curtain design, DUAL-FREEZER high speed cold storage doors prevent condensation and ice buildup while preserving frozen goods.
This makes it ideal for cold room environments with temperatures down to -20 degrees, such as warehouses and industrial units with refrigerated compartments.
Please note that these doors are designed to separate two negative temperature environments (without the need for a hot air blower).
Superior Temperature Control
DUAL-FREEZER high speed cold storage doors excel at maintaining stable temperatures in frozen compartments. Key features include:
Innovative Double Curtain Design – The door is composed of three layers: a PVC curtain – ventilated air chamber – and another PVC curtain. The air chamber creates an effective thermal barrier, minimising temperature fluctuations in the cold room.
Impact Resistant – The door is made with impact-resistant materials, minimising damage from collisions that leads to temperature instability and product loss.
Fast Action – The DUAL-FREEZER has a fast max opening speed of 1.2 m/sec and closing speed of 0.8 m/sec. This prevents temperature fluctuations caused by the ingress of warm air.
Energy Efficient and Cost Effective
The DUAL-FREEZER high speed cold room door offers several benefits for energy efficiency and cost-effectiveness. Here’s what to expect:
No Heating System – The DUAL-FREEZER does not include a heating system, meaning you save money on energy costs while being more sustainable.
Inexpensive Replacement Door Bars – The door’s lightweight plastic horizontal bars are inexpensive to replace in case of impact damage.
Safety Light Curtain – The safety light curtain system on the legs uses a beam to detect obstructions. When it detects an obstacle, it reserves the direction of the curtain, preventing impact damage that results in inconsistent temperatures and product spoilage.
DUAL-FREEZER® FAQs
What is the maximum size of the DUAL-FREEZER® cold storage door?
The DUAL-FREEZER cold storage door can have a maximum width of 4 m and height of 4 m. The size of the compartment must be at least 2 m wide and 2.5 m high.
Can the DUAL-FREEZER® be used between environments at a temperature of +20° and -20°?
No, the DUAL-FREEZER cold room door can work down to -25° but must be combined with an insulated sliding freezer door to avoid temperature changes and condensation with the subsequent formation of ice.
Can I use the DUAL FREEZER without an insulated sliding cold room door?
No, the DUAL-FREEZER cold room door must always be combined with the insulated sliding cold room door.
Can the DUAL-FREEZER® door have windows?
No, the DUAL-FREEZER cold room door cannot have windows because this would compromise the functionality of the door.
Furthermore, the cover is a double PVC sheet so visibility through these windows wouldn’t be possible.
Does the DUAL-FREEZER® door have a heated curtain?
No, the DUAL-FREEZER cold room door does not have a heated curtain.
In the event of malfunctioning of the insulated sliding door, this would lead to the creation of condensation and ice that is dangerous for operators.
What’s the difference between a DUAL-FREEZER and AUTO-FREEZER?
The DUAL-FREEZER is designed to separate two negative temperature environments. The DUAL-FREEZER must always be combined with a sliding insulated door to avoid temperature fluctuations that result in condensation and ice.
In contrast, the AUTO-FREEZER can separate a negative and positive temperature environments. It includes a hot air blower to continuously combat condensation and ice.
This heated blower allows the AUTO-FREEZER to operate at lower temperatures (down to -25°C) than the DUAL-FREEZER (down to -20°C).
