Industrial and commercial compressed air systems engineered for consistent pressure, clean dry air and minimal energy consumption — from compressor plant sizing to point-of-use distribution.
Service Overview
What we deliver
Compressed air is often called the fourth utility, and it is usually the most expensive one per unit of useful energy. TechMEPi Engineering designs and supervises compressed air systems for industrial and commercial facilities — manufacturing plants, workshops, food and beverage facilities, laundries and buildings that rely on pneumatic tools, actuators and controls. Our objective is simple: consistent pressure and air quality at every point of use, at the minimum energy cost, backed by 18+ years of mechanical building services experience across six countries.
Poorly designed compressed air systems waste energy in well-documented ways: leaks that can silently consume a large share of compressor output, pressure set higher than any process needs, undersized piping that forces compressors to work against artificial resistance, and treatment equipment mismatched to the air quality actually required. Good design eliminates these losses before they are built in.
Our Approach
We begin with a demand study: which processes use air, at what flow and pressure, with what duty cycles and diversity. That profile drives compressor selection — fixed-speed machines for stable base load, variable-speed units to follow fluctuating demand, and standby capacity where production cannot stop. Receiver vessels are sized to smooth peaks and reduce compressor cycling.
Air treatment is matched to the application, not maximised by default. Dryers, filtration stages and oil removal are specified to the air purity classes of ISO 8573 appropriate to each point of use — food-contact and instrument air demand far more than a tyre bay, and treating all air to the strictest class wastes energy and capital. Distribution is designed as a ring main where layout allows, sized for low pressure drop, with proper condensate drainage, isolation valving for maintenance and correctly detailed drops to each workstation. Plant room ventilation and heat recovery from compressors are considered from the outset, because compression heat is free energy most facilities simply reject. Where compressed air serves critical production, we plan redundancy and maintenance bypasses so a compressor service never stops the line, and we supervise installation as carefully as design — leaks are born at poorly made joints.
What We Deliver
A typical compressed air engagement includes:
Air demand assessment and load profiling
Compressor plant selection and standby strategy
Receiver sizing and pressure control philosophy
Air treatment specification to ISO 8573 purity classes
Ring main and drop-pipe distribution design
Condensate management and plant room ventilation design
Installation supervision, testing and commissioning witnessing
Standards and Compliance
Systems are designed to recognised international practice, with air quality specified to ISO 8573 classes and pressure vessels and safety devices handled in line with published pressure equipment safety codes and local statutory inspection requirements. Documentation includes the schedules and test records needed for regulatory inspection and insurance. We also design for measurement — flow and power metering points are included so the plant's efficiency can be verified in service, not just promised at tender.

FAQ
Common Questions
What size compressor does my facility need?
Sizing starts with a demand study, not a catalogue. We list every air-using process with its flow, pressure and duty cycle, apply realistic diversity, and add a margin for leakage and growth. The profile then determines whether one fixed-speed machine, a variable-speed unit or a combination serves you best. An oversized compressor short-cycles and wastes energy; an undersized one starves production. The study is quick and pays for itself.
Why are our compressed air running costs so high?
Usually a combination of leaks, excessive system pressure and inefficient part-load control. Leaks alone can consume a substantial share of compressor output in an unmanaged system, and every extra bar of pressure raises energy consumption measurably. We audit the system, quantify the losses, and correct them through leak reduction programmes, pressure optimisation, receiver and control changes, and — where justified — compressor replacement with verified payback figures.
Do we need oil-free compressors?
Only if your processes demand it. Food-contact air, pharmaceuticals, electronics and some instrument air genuinely require the higher ISO 8573 purity classes that oil-free machines or rigorous filtration provide. General workshop and pneumatic tool air does not. Because oil-free plant costs significantly more to buy and maintain, we specify purity point by point — strict where the process requires it, economical everywhere else.
Can the system be designed for future expansion?
Yes, and it should be. We size distribution mains with spare capacity, arrange plant rooms with space and connections for an additional compressor, and select control systems that can sequence extra machines later. Building in expansion capacity at design stage costs little; cutting into a live ring main and re-piping an operating factory later is expensive and disruptive. Tell us your growth plans and we design for them.
