Common questions

How quickly can a coldroom be back at temperature?

Once the fault is cleared, a well-insulated coldroom pulls back down within two to four hours. We advise on stock protection during that window.

Do you top up gas without finding the leak?

No. A weighed charge into a leaking system is money out the window, so the leak is found and repaired first, then the system is evacuated and charged to the plated weight.

Can you work after trading hours?

Yes. Retail, restaurant and office work is routinely scheduled at night or early morning under a permit-to-work so trading is not interrupted.
