Air-Cooler Bundles
Have it your way – replacement-in-kind or upgraded!
Altex can build you a replacement air-cooler(aerial fin-tube) bundle matching original equipment manufacturer drawings.
Or maybe the original design is not meeting your needs – we can upgrade the design to:
- Increase cooling capacity for flows, temperatures, and/or duty
- Upgrade metallurgy
- Solve performance issues – fouling, corrosion, freezing
- Re-rate design temperature and pressures
Re-tubing air-cooler bundles is a great alternative if you have the time! This can be performed economically in our shop or via our field service team.
Altex has built and repaired hundreds of air-cooled bundles over the past 20 years in our two divisions – shop fabrication and field services. Additionally, we can provide the spare parts needed to keep your coolers running:
- Header plugs, taper tube plugs
- Louvres, linkages, actuators
- Fans and anti-rotation devices
- Motors
- Drive components – Bearings, shafts, sheeves, belts, guards
- Bug screens, hail guards, doors, floors
- Instrumentation - Averaging RTD, thermo-couples, transmitters, vibration switches & sensors
- Heating coils – steam and glycol
- Space heaters – gas and electrical
