Frequently asked questions.

We are an industrial HVAC and refrigeration engineering company. We design, supply, install, commission and maintain ammonia plant systems, VRV and VAV systems, chilled-water systems, coldrooms and fire-protection systems for industrial and commercial facilities.

We work with food and beverage, cold-chain and logistics, pharmaceutical, manufacturing, data centre, commercial, retail and hospitality clients. If your facility needs reliable cooling, climate control or fire protection, we can help.

Yes. We deliver new installations, upgrades and retrofits of existing plant, as well as ongoing maintenance and breakdown support.

VRV (variable refrigerant volume) controls the flow of refrigerant to indoor units for precise, zoned heating and cooling. VAV (variable air volume) controls the volume of conditioned air delivered through ductwork. We help you choose the right approach for your building.

Ammonia (NH₃) is highly energy-efficient, has zero ozone-depletion and zero global-warming potential, and performs extremely well for large-scale industrial and cold-storage cooling. It requires careful, compliant engineering — which is our speciality.

Yes. We deliver coldrooms, freezer rooms, blast freezers and large cold stores as a single package — insulated panels, refrigeration, doors, flooring, controls and monitoring — sized to your product and throughput.

Yes. We design and install sprinkler, pump, hydrant and suppression systems to current standards, either as part of an integrated mechanical package or as a standalone installation, with testing and certification.

Yes. We supply, charge and recover the full range of common refrigerants — R22, R410A, R134a, R404A, R407C, R507 and R32 — along with leak detection, gas conversions and safe recovery. See our Freon & Refrigerant Gas page.

We'd rather find the leak. Refrigerant is a sealed charge, so a system that keeps losing gas has a fault. Repeated top-ups cost more over time and let refrigerant escape, so we trace and repair the leak first, then recharge to specification.

We consult to understand your facility and goals, engineer the right system to specification, supply and install it with qualified teams, then commission, certify and support it. You deal with one accountable team throughout.

Yes. We regularly integrate with building-management systems and coordinate with other trades and contractors on site.

Yes. We provide planned preventative maintenance to keep systems efficient, compliant and reliable, plus responsive support when you need it.

We offer service and breakdown support to minimise downtime. Talk to us about a maintenance agreement suited to your facility's criticality.

Yes. We deliver to current safety standards and regulatory codes, with documentation and certification provided on completion.

Ammonia plant is engineered with appropriate gas detection, ventilation, alarms, pressure-relief and safety systems, and maintained to keep it compliant and safe throughout its life.
