Coiled tube heat exchangers for cooling in tunnelling and mining
Heat exchangers for dusty and aggressive air conditions
WAT coiled tube heat exchangers are air/water heat exchangers that are designed in particular for application in dusty and aggressive air conditions. These heat exchangers are characterized especially by their positive system features:
- High heat transition coefficient
- Low pressure loss
- Robust design for underground application
- Trouble-free operation with minimal dust deposit
- Easy maintenance through fast cleaning
- Water-side operating pressure up to 63 bar
Air-Cooler
type RWK and SPK

Your benefits:
WAT air-coolers can be used everywhere, where specific high requirements are imposed on air-cooling, e.g. for application in underground roads or long walls as well as on a TBM’s back-up system.
- Heat exchangers with cooling capacity from 25 kW up to 2,000 kW
- Air/water heat exchangers for application at underground or on a TBM
- Water-side operating pressure up to 63 bar
- Explosion-proof design (ATEX group I Category M2 for mining)
Re-Cooler
type RK

Your benefits:
WAT re-coolers are especially used, when only an underground re-cooling by air is possible and high requirements on re-cooling are imposed because of the air conditions.
- Heat exchangers with cooling capacity from 100 kW up to 1,500 kW
- Underground evaporative cooling tower (constant water supply necessary)
- Water-side operating pressure up to 63 bar
- Explosion-proof design (ATEX group I Category M2 for mining)
