Dryair 2500 VRF(s)
This project came from our distributor / agent in Singapore where a pharmaceutical plant required additional dehumidification in one of it's production lines. Due to footprint restrictions we were required to redesign the overall size of the unit without loss of performance - our engineers set about squeezing the components into a chassis that is approximately 25% smaller than we would normally provide.
To solve the space problems we designed and fabricated our own process fan system to cope with the airflow but be physically smaller (see below). We incorporated our clever 'slide-in' rotor and regeneration section and a 'swing out' controls panel (see below) all which helped to save space. The unit features a manual control damper with an automated fresh air inlet for fine control of the process air.

Yet another Desiccant DryAir technological breakthrough...a specialised MTHCU (Medium Temperature Humidity Control Unit) 75 VRF(s) unit with built in chiller unit designed to be super mobile and incredibly compact with some clever features.
built-in chiller / refrigeration unit creating cooling down to 10 ℃ (dependent on ambient conditions)
slim and compact design freeing up floor space
available in variations from 75 VRF up to 300 VRF (larger airflow options in the future)
ultra efficient energy saving motors
clever design allows the machine to slide apart for easy maintenance
Our 3D designers were presented with many problems by this client but eventually managed to fulfil the criteria set, the final design came to fruition through some innovative thinking and ‘stretching’ the laws of physics!
This clever little unit has undergone testing and is being shipped to the client as I write this, we have orders for five more.

Here are some images of the finished ‘improved’ LTHCU - it is tested and shipped, this amazing peice of engineering is now operating at an incredible -40 ℃ and the client wants another two.

We have recently begun to manufacture and supply our own Desiccant Rotor Cassette to customers who already have desiccant technology but require a bespoke solution when replacing this main component, we decided this was a good idea because we found that current suppliers couldn’t make bespoke sizes either quickly enough or cheaply enough and sometimes not at all. We have already fabricated and sold two 400mm deep cassettes to a Turkish customer. Please visit our page dedicated to this service by following this link.

We have just completed a Dryair 40000 VRF(s) for a stock cube manufacturing plant run by Unilever in Nigeria, the machine was commissioned by Comfort AirCon of Lagos. Fabricated in stainless steel, it is one of the largest single machines we have built in this material. The unit has passed factory testing and has been shipped, this is the largest machine we have ever factory tested for a client and involved 12 bar of steam, hiring in a 370Kw chiller and generator to power the chiller & a 80Kg/hr humidifier to saturate the air in. Below are pictures of the finished machine prior to packaging & shipping.
May / June 2010
Currently, we are preparing our manufacturing facility for the onset of a large order with another far eastern customer for two 8 metre long dual wheeled dehumidification AHU’s, the project is due to be started this week and will take 9 weeks to complete. Keep an eye on this page for pictures of the completed AHU’s and info on their specifications. We will be creating a video covering the manufacture of these incredible machines.
Update...September 2010
The two large desiccant machines are now shipped and installed at the showcase stadium in Doha, Qatar. Our engineers are out in Qatar at the moment integrating the system into the stadium BMS. We have created a dedicated page to this amazing project, please click this link.
May / June 2010
We have been commissioned to design, manufacture & install a Dryair 4000VRF desiccant AHU at a major american pharmaceutical research facility in Britain, alongside a 200VRF for a smaller separate room. The AHUs are currently under construction and we have shot some ‘work in progress’ pictures...
The project has also included major lagged ductwork configuration built & installed on site and has a water chiller attached, we anticipate the machine(s) to be finished within the next two weeks with commissioning by the end of June.
June 2010
Here is the finished AHU, which is now on the roof of the pharmaceutical manufacturing facility, ductwork has been fitted and we are now undertaking commissioning trials of the system.
Latest...
The AHU, drying room extension and ducting system are now fully operational and the client is again in full production.

We have just completed a prototype AHU for a Korean client. It is a Low Temperature Humidity Control Unit (LTHCU) formed in two sections sat on top of one another. The unit had to be mobile and was therefore mounted on wheels. The client has ordered a further 3 machines of the same spec and these are currently under manufacture. There are images here of the finished unit and a close up of the bottom half, we are particularly proud of the control panel electronics in as this machine was extremely complex to control and we had very limited space. You can download a Pdf brochure about this remarkable machine by clicking here.

We have just finished this very smart little self-contained, packaged unit for a pharmaceutical customer in Pakistan, it is specialist 200VRF connected to a chiller with electronic control and skid mounted for combined temperature and humidity close control.
Dryair 75 VRF
DDSL are proud to launch our most compact unit ever, the Dryair 75 VRF. We have recently completed an order for 600 units to an overseas military customer for use in controlled humidity environments to be completed in batches of 25 over the next 40 months. We are also currently manufacturing a further 200 stock units for the UK hire industry.
Features
Versions are available as, skid mounted incorporating chilled water for close temperature control, a total humidity control system and a pumped condensing unit for applications where it is not possible to vent regeneration air outside.
