Howden Screw Compressor May 2026

The slide valve and stepless capacity control are smooth. From 100% down to 25% load, the compressor maintains stable discharge pressure without surging. The Vi (volume ratio) adjustment is also effective for varying suction pressures.

First cost is your primary metric, or your application is light-duty (less than 4,000 hours/year). howden screw compressor

Rating: 4.6/5 Best for: Heavy industrial continuous duty, process gas compression, and large-scale refrigeration. Overview Howden is a legacy brand in the compressor world (founded in 1854), and their screw compressor range—including the WRV, H系列, and twin-screw oil-injected models—is considered a benchmark for durability. This review is based on field performance of a typical Howden twin-screw compressor (e.g., WRV 255) operating in a petrochemical plant over 18 months. The Good (Pros) 1. Unmatched Build Quality The casing and rotors are machined from high-grade cast iron or forged steel. There’s no flex under load. The rotor profile (Howden’s proprietary “X” profile) is precision-ground, resulting in minimal internal leakage. In our plant, vibration levels remained consistently below 2.0 mm/s even at 100% load. The slide valve and stepless capacity control are smooth

Oil change intervals are rated at 8,000+ hours (vs. 4,000–6,000 for budget brands). Bearing life is conservatively rated at 50,000 hours. After 12,000 hours, our unit showed no measurable rotor wear. The Bad (Cons) 1. High Initial Cost (Premium Tier) A Howden screw compressor typically costs 30-50% more than a comparable Chinese or Eastern European brand. You are paying for longevity and efficiency, but the capital expenditure (CAPEX) is a barrier for small operations. First cost is your primary metric, or your

The Howden screw compressor is the “Mercedes G-Wagon” of rotary screws: over-engineered, expensive to buy and fix, but nearly unstoppable when properly maintained. It’s not for everyone, but for critical process applications, it’s a justifiable investment.

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.

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.
