A busy metal fabrication and welding specialist in Waterlooville, Hampshire, has just taken delivery and professional installation of a brand-new Hertz HGS 7 rotary screw compressor package – replacing their tired and unreliable 15-year-old Almig Combi unit that was costing a fortune in repairs and downtime.
The Problem: An Ageing Almig Combi Holding Back Production
The customer’s previous Almig combination unit (compressor + dryer + tank) had served well for many years but was now suffering from repeated belt failures, high running costs, and increasingly frequent breakdowns. With fabrication orders stacking up, they needed a modern, dependable solution – fast.
The Solution: Hertz HGS 7 Complete Package
Airlink Compressors supplied and installed a full turnkey Hertz HGS 7 system, including:
- Hertz HGS 7 rotary screw compressor (7.5 kW) – German-engineered for outstanding efficiency and reliability
- 250-litre painted air receiver – vertically mounted to save valuable floor space
- Integrated refrigerant dryer with pre- and after-filtration for clean, dry air essential in precision metalwork
- Electronic zero-loss condensate drain
- High-efficiency oil-water separator for environmentally responsible condensate management
The Hertz HGS 7 matches output exactly to the workshop’s demand (from plasma cutting to pneumatic clamping and grinding), delivering energy savings of up to 30% compared to the old fixed-speed Almig.
Seamless Installation with Zero Production Downtime
Our Hampshire-based engineering team removed the old Almig unit and installed the new Hertz package over a single weekend, meaning the workshop was back at full capacity first thing Monday morning – with no lost production.
Workshop Manager commented:
“The difference is night and day. It’s quieter, uses far less electricity, and we finally have dry air without water in the lines ruining welds and paint finishes. Airlink made the whole swap painless.”
