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.
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.
Why is my ice cloudy or melting too fast?
Cloudy, soft ice means the freeze cycle is being cut short or the water is carrying too many dissolved solids. We test hardness and TDS on site, fit the right filtration, descale the plate and re-time the cycle so cubes freeze clear and hard.
Is scale really a problem for ice machines here?
Yes, it is the single biggest cause of lost output on this water supply. Scale insulates the evaporator, so the machine runs longer for less ice and eventually pits the plate. Regular descaling is far cheaper than an evaporator replacement.
