Refrigeration Door Seal Heating
- For OEM Installation
Keeps containers free of frozen door problems
When a blast freezer or chiller trailer door is frozen solid, it becomes a major problem for the customer.
They need their product out, and every hour is costly to them.
They will use any means to gain access, including breaking the door open.
Electrical trace heating is notoriously unreliable for trailer door seal heating due to inherent hot spots, which eventually lead to the failure of the element.
That’s why OEMs are switching to one of ZECK’s patented solutions: a solid-state heater inside a bespoke extrusion, giving long-term reliability and bringing peace of mind for the OEM renter that he can fit-and-forget.
No more service callouts for failed units, or doors broken with forklift trucks by customers who can’t wait to get access to their precious goods.
Choose the right system for your container
ZECK can tailor-make an extrusion and heater for your style of container, whether it be a chiller or blast freezer.
As each manufacturer of chiller doors has a different design.
If you need a ZECK solution to seal heating, ZECK will design and invest in an extrusion tool if you have the volume requirement.
The extrusion forms the key to good seal heating through conduction in the aluminium. Getting the right profile for your door is key and ZECK can design this for you.
“We love the ZECK system, we tested it extensively before committing. It’s easy to fit and performs fantastically.
We purposely froze a door solid by spraying water at the seals and leaving the chiller running overnight at -40°C.
We switched the ZECK system on and within 15 minutes we could open the doors. Amazing."
