EST. 2007 // KOVEN AIR MFG

The first chiller we built is still running.

Koven Air shipped its first screw chiller in 2007. It is still in service today. Since then we have grown into a manufacturer of air handling units, rooftop packages, chillers, heat pumps, fan coils and desiccant dehumidifiers — most of them built to a specification that did not exist before the project. Our equipment now runs in more than 35 countries.

Our history

A manufacturer, not a trading company.

Koven Air Environment Technology Co., Ltd. builds mid- to high-end environmental control equipment for industrial, commercial and agricultural buildings. We design and assemble everything in our own plant in Suzhou Industrial Park, which is why we can quote a unit that does not exist yet — and stand behind it afterwards.

2007

First screw chiller

The company is founded and builds its first screw chiller. The unit is still in operation today, nineteen years on.

2010

Koven Air becomes a brand

We stop building only to order for others and start exporting under our own name.

Koven Air Manufacturing Facility
Today

35 countries, one plant

Users across North America, Southeast Asia, the Middle East and South America, with average annual growth above 25%.

Inside the factory

20,000 m², one continuous flow.

Sheet metal arrives at one end and a tested unit leaves at the other. Nothing is subcontracted out and back, so a change to your specification does not mean chasing three suppliers. Robot cells handle the modular line work; every step is recorded against the serial number.

What we build

Six product lines, sized to your project.

Selection starts from your design conditions, not from a catalogue page. Tell us the capacity, airflow, static pressure and the climate the unit has to work in, and we return a calculation you can check.

SYS.01
Air Handling Units

AHU

Air Handling Units

Modular sections you specify: cooling, heating, heat recovery, filtration, humidification. Built to the airflow and external static pressure the project asks for.

SYS.02
Packaged Rooftop Units

Rooftop

Packaged Rooftop Units

Cooling, heating and fresh air in one weatherproof cabinet, for retail, warehousing and light industrial roofs.

SYS.03
Fan Coil Units

Terminal

Fan Coil Units

Concealed, ceiling and floor types for terminal cooling and heating in offices, hotels and hospital wards.

SYS.04
Heat Pumps

Heating

Heat Pumps

Air and water source units for heating, cooling and hot water on sites without a combustion supply.

SYS.05
Industrial Chillers

Chillers

Industrial Chillers

Screw and scroll, air-cooled and water-cooled. The line we started with in 2007 and still the core of the plant.

SYS.06
Desiccant Dehumidifiers

Dehumidification

Desiccant Dehumidifiers

Rotor dehumidification for rooms needing a dew point below what refrigeration alone can reach — battery dry rooms, pharmaceutical suites, grain stores.

Projects served

Equipment supplied to sites operated by:

Tesla Gigafactory Samsung Electronics BMW automotive plant Yadea Hilton Shanghai World Expo Bay Air

“For the Indonesian medical market we developed a heat-recovery AHU with negative-ion treatment that had no equivalent in the range — one of the reasons customers come to us rather than to a catalogue.”

Certification

Paperwork your inspector can verify.

Export projects fail on documentation more often than on hardware. Test reports and certificates are issued with the unit, and we will send them for review before you place the order.

How we work with you

The engineer who quotes it is the engineer who answers later.

Most of what goes wrong on an HVACR project happens after the container leaves. These are the three points where we stay involved.

01 Before the order

Selection you can check

We work from your project design and verify the parameters ourselves — capacity, airflow, static pressure, temperature and humidity control — then return the calculation so your engineer can confirm it against the local climate and building type.

02 In production and on site

Tested before it ships

A unit leaves only after it is built and tested without fault. Our technicians guide installation and commissioning on site, and make modifications where the site does not match the drawing — which it rarely does exactly.

03 After handover

Support for the life of the unit

Free technical guidance for as long as the equipment runs. Problems inside the warranty period are handled without delay, and we train contractors and engineers on the equipment on a regular schedule.

What arrives with the quotation

Distributors, consulting engineers and design institutes ask for the same six documents. You do not have to ask for them twice.

Selection calculation

Performance curves

CAD & BIM files

Control logic description

Wiring diagrams

Installation & commissioning manual

Start a project

Send us the conditions. We will send back the calculation.

Design conditions, building type, capacity and the climate it has to survive — that is enough for us to start. We reply in English, and we reply to engineers directly.
