Matching details for Spare Heat units
The Spare Heat specs page lists the identifying details needed when ordering replacement heater parts. Use it to match the correct element or bank to the dryer already on your floor.
Identify the exact replacement heater used in a Spare Heat flash dryer or heat bank. Record the heater type, overall size, voltage, wattage, and the lead exit position before ordering. Ceramic tiles, quartz tubes, and complete banks are not interchangeable without checking the frame and wiring layout.
Begin with a clear photo of the heater face and the rating plate on the dryer. Include measurements across the active heating area and note whether the element sits in a single-bank or twin-bank arrangement. These details help distinguish a full bank replacement from a single failed element.
Checks before ordering parts
Inspect the terminals, ceramic holders, reflectors, and supply cable for heat damage while the unit is isolated. A cracked tile, blackened quartz end, or warped reflector can point to more than one part needing replacement. Also note whether the dryer runs on single phase or three phase supply, as that affects the correct spare selection.
Site conditions that affect spares
South African print rooms often deal with dust inland and salt air near the coast, both of which shorten cleaning intervals around heater banks. In Johannesburg and other Highveld sites, lint and fine dust can dull reflectors and trap heat around terminals. Durban and Cape Town sites should check corrosion on connections and fixings before fitting a new element.
Power interruptions matter when diagnosing a failed heater. After load-shedding or unstable supply, check contactors, fuses, and control settings instead of assuming the element alone is at fault. A replacement part will only perform properly if the bank is receiving the correct voltage under load.

Numbers to gather from the dryer
Write down any model marking shown on the Spare Heat unit, plus the heater dimensions in millimetres. Count the number of elements in the bank and note the spacing between them.
If the original label is unreadable, use photos of the housing, reflector tray, and terminal side to help identify the correct part. Include the application temperature setting or usual flash distance if the unit is used on garments, sleeves, cartons, or labels.
