Howden Screw Compressor High Quality 🔖

The cast-iron casing makes these compressors significantly heavier than rotary vane or scroll alternatives. For mobile or space-constrained installations (e.g., offshore platforms), this is a real issue.

Compared to older screw compressors, the Howden delivered a 12-15% reduction in specific power (kW per CFM). The asymmetric rotor profile minimizes blow-hole losses. For a 500 kW motor, this saves roughly $15,000–$20,000 annually in electricity. howden screw compressor

First cost is your primary metric, or your application is light-duty (less than 4,000 hours/year). The asymmetric rotor profile minimizes blow-hole losses

While service intervals are long, when something breaks, parts are expensive. A set of main bearings can cost $3,000–$5,000, and an OEM rotor replacement is nearly the cost of a new unit. Additionally, servicing requires specialized tooling and Howden-trained technicians—local general mechanics cannot handle it. While service intervals are long, when something breaks,

Oil-injected Howdens require strict oil quality (typically synthetic, ISO VG 68–100). Using non-approved oil degrades performance and voids the warranty. The oil separator elements are effective but expensive ($800–$1,500 each).
