Calorifier Repairs in Johannesburg & Gauteng

Steam and hot water calorifier coil, control valve and tank repairs.

Calorifiers fail predictably: the coil scales or perforates, the steam control valve sticks, or the condensate trap fails and floods the coil. A perforated coil shows up as rising tank pressure or contaminated condensate and needs isolation before it damages the rest of the circuit.

Turnaround
Coil replacement usually needs an isolation window; scoped after testing.
