Long Freeze Cycles in Tembisa

Long Freeze Cycles in Tembisa, East Rand. Freeze cycles take far longer than the manufacturer's timing.

Urgency for this fault is normally priority. Ekurhuleni visits are grouped by area so restaurant and factory ice plant can be attended on the same run.

The ice plant here is mostly estate clubhouses, guest houses, small restaurants and private bars, so the work is weighted towards undercounter and small modular machines. Filtration sized on measured hardness and throughput is the cheapest protection available for an ice machine's water circuit and pump.

We diagnose in order of likelihood rather than replacing parts speculatively: clean condenser and re-time the cycle, then descale the water circuit, then read pressures, superheat and subcooling.

FAQs

Frequently asked questions

What causes long freeze cycles?

The usual causes are dirty condenser or high ambient, scaled evaporator, low charge or restricted metering device, water temperature too high. Which one applies is settled on site by measurement, not guesswork.

How quickly can you attend in Tembisa?

Priority attendance applies to this fault. Ekurhuleni visits are grouped by area so restaurant and factory ice plant can be attended on the same run. Call 069 268 0988 for the next available slot.

How is it diagnosed?

Clean condenser and re-time the cycle; Descale the water circuit; Read pressures, superheat and subcooling; Log inlet water temperature; Assess compressor differential.

Is this common on modular ice machines & bins?

Bin insulation and gasket condition decide how much of the night's production survives to breakfast service. On modular ice machines & bins in Tembisa we see this fault regularly, usually alongside overdue descaling.

Which service will fix it?

Ice Machine Servicing normally resolves it. Half a day per machine, including refill and a full production cycle.

Can we keep operating in the meantime?

Sometimes — where the fault is a water-side problem the machine can often be run on reduced output until parts arrive. Where a compressor or leak is involved we advise buying in bagged ice while the repair is completed.
