Heating & Cooling Coils

Replacement coils built to your existing dimensions

Tube diameter: 3/8 – 5/8 inch copper
Fins: Hydrophilic-coated aluminium or copper
Selection: AHRI-certified software
Testing: Hydrostatic, every coil

AHRI Certified Coil selection
ISO 9001 Quality management

Overview

A coil is where an air handling unit does its work, so its duty has to be right on paper and in the unit. We design chilled water, DX and heating coils on AHRI-certified Unilab selection software, so the capacity on the submittal is the capacity the coil is built to.

Tubes are high-efficiency copper from 3/8 to 5/8 inch; fins are blue hydrophilic-coated aluminium or copper. Every coil is hydrostatically tested before it leaves the factory, and in our own units coils sit on a sliding mechanism above a rustproof condensate pan, so they can be withdrawn for maintenance.

We also build coils on their own — for other units, and as replacements made to the dimensions of the coil already installed — and supply them to customers worldwide.

Replacement Coils

A like-for-like coil for the unit you already have

Exact fit

A 100% match to your unit's original dimensions and technical specifications, for a direct, seamless installation on the same mounting and connection points, with no modification on site.
AHRI-certified selection

Coils are selected and sized on internationally recognised AHRI-certified software, so cooling capacity and airflow match the original performance 100%.
Every application

Available for all applications and systems (Chilled Water - Heating).

Certifications & standards

What each mark on this product means, who issues it and how it applies here.

All certifications & standards

AHRI Certified

Coil Selection (Unilab)

Issued by Air-Conditioning, Heating, and Refrigeration Institute (AHRI), USA

What it is

AHRI runs independent performance certification for HVAC equipment and selection software. Products are tested in third-party laboratories, and a certified rating has to match the measured result within set tolerances.

On this product

The coils are selected on AHRI-certified Unilab software, so the capacity quoted on your submittal is the capacity the coil delivers when it is tested.
ISO 9001

Quality Management Systems

Issued by International Organization for Standardization (ISO)

What it is

The international standard for quality management systems. A certified company works to documented processes, checks its output against them, records what it finds and corrects the cause of any fault, and is audited on all of it by an independent certification body.

On this product

Designed, fabricated and inspected under our certified ISO 9001 quality system: the same documented process for every unit, whichever of our factories builds it.

Can you replace a coil in a unit from another manufacturer?

Yes. We build replacement coils to the dimensions and connections of the coil already installed, selected for the duty it has to deliver.

Why hydrophilic-coated fins?

The coating lets condensate spread and drain off the fins instead of beading between them, which keeps the air path clear on a wet cooling coil. Copper fins are available where the environment calls for them.

How is each coil tested?

Every coil is hydrostatically pressure tested before it leaves the factory or goes into one of our units.
