New Mobile Humidifier From Condair
Story
Condair is launching the new Condair PureHum 1000 Pro, a mobile humidifier that is ideal for areas up to 1,000m³. Advanced features include phone-based app control, UV-water sterilisation, multiple air filtration options and an 8-speed auto-adjusting fan.
Mobile humidifiers are often used in museums and art galleries, where humidity control can be a temporary requirement during an exhibition period. A mobile humidifier is a great solution, as it is easy to set-up, use and then store when not needed. The Condair PureHum 1000 Pro is ideal for this application, due to its subtle but modern design, tamper-proof control system and lockable castor wheels.

A large 50 litre water tank means the humidifier can be used where there is no available plumbing and won’t require frequent re-filling. A UV-water sterilisation system treats the water with ultraviolet light to kill germs and combat microbial growth. The humidifier can also be plumbed-in with a mains water connection and drain. When plumbed-in, a flushing feature ensures water will not remain in the system to stagnate, further enhancing hygienic operation.
With a maximum output of 2.7 litres per hour, the unit is ideal for a small to medium sized room. A top-mounted touchscreen control panel provides data on current room conditions, water level and operating parameters. A safety glass cover prevents tampering, whilst allowing the screen to be viewed. A remote humidistat sends a wireless signal to the PureHum 1000 Pro, to manage output in line with the desired room humidity level. When multiple units are used across an area, control can be centralised via a single humidistat or managed individually with one humidistat per humidifier.
In addition to the integrated controller, a PureHum app allows users to control the humidifier and see all operating parameters from their mobile phone. Available on the App Store or Google Play, this feature is enabled via an optional WLAN/wifi module.
The Purehum Pro 1000 can offer the additional benefit of air purification as well as humidity control. As standard the unit come with fine dust and F7 air filters. Optionally a HEPA H10 filter can be chosen, which is capable of captures 85% of particles over 0.5 microns in size. Lastly an activated carbon filter can also be employed to remove odours and gases from the air, including volatile organic compounds (VOCs).

Condair Helps Konvekta Achieve 92% Energy Recovery
Story
The Condair ME evaporative humidifier is being used by energy recovery specialists, Konvekta, as one of its standard adiabatic cooling solutions. The humidifier is being incorporated into Konvekta’s exhaust air cooling systems to help Konvekta deliver up to 92% annual energy recovery to its clients’ buildings.
A Konvekta exhaust air cooling system pre-cools incoming fresh air to reduce a building’s need for mechanical cooling. The Condair ME humidifier is used in this system to provide very low energy evaporative cooling to the warm air extracted from the rooms. Before the cooled extract air is vented externally, it is run through a heat recovery system and provides up to 10K of cooling to the incoming fresh air supply. A cooling effect from 32°C outside air temperature down to 22-23°C supply air temperature can be reached, without any mechanical cooling.
Amir Ibrahimagic, Group Business Development Manager at Konvekta, comments, “Konvekta has standardised its exhaust air cooling systems on the Condair ME humidifier as its evaporative cooling solution. The reliability of the unit is second-to-none. It incorporates the highest quality components that give utmost longevity and performance to our clients. Alongside the product’s USPs, Condair is also a very solutions-oriented partner. As a Konvekta energy recovery system is always custom designed for a client’s needs, it’s vital for us to have flexible design support from our evaporative cooling supplier.”
Amir continues, “As an example, a recent installation at a clinic in Tyrol, Austria, resulted in a confirmed annual energy recovery across the Konvekta systems of 92% for the building. A single Condair ME humidifier contributed more than 60,000kWh/a of cooling during this period from just 3,800kWh/a of consumed electricity. This low energy cooling significantly improved the building’s overall energy efficiency and helped our client become the most sustainable clinic of its type in all of Austria.”

Konvekta are a leading global supplier of high efficiency run around energy recovery systems, with clients including MIT and Harvard University in the USA, as well as Frankfurt Airport, Germany, and Swarovski Optik in Austria. Its systems offer an average annual ROI of between 3-7 years, depending on energy prices and operating hours. Alongside the highest efficiency systems on the market, the company offers a performance guarantee to clients, covering highly detailed financial and operational outcomes.
The company’s Konvekta-Controller operates within a Digital Twin framework and provides net annual energy-saving calculations to design engineers early in the design phase. Following installation, the Konvekta-Controller presents current and historical performance data, allowing optimisations to be carried out to meet or exceed initial design projections.
The Condair ME in-duct adiabatic humidifier can be used to provide humidification or cooling to an air handling unit. Its evaporative matrix is located inside the duct and has water flowing down its surface. Air passing through the matrix is humidified and cooled without any aerosols being produced inside the AHU. The Condair ME has an innovative hydraulic pump module that can be located either inside the duct or externally, which allows servicing to happen without any AHU downtime. Units are available in sizes ranging from just 60x62cm to over 4x4m, with total outputs from a single unit of up to 1,200kg/h. In terms of cooling, this can equate to 822kW of adiabatic cooling from as little as 1kW of consumed electricity.
The Condair Group is the world’s leading specialist in humidity control and evaporative cooling, with energy efficient, hygienic and innovative technologies for commercial, industrial and heritage applications. Condair supports its clients from the initial system design advice, through supply and install, with nationwide after-sales service and maintenance.

Podcast: How To Control Static By Controlling Humidity
Story
In this short interview with Business Net Explorer, Dave Marshall-George, Sales Director at Condair, explains why static build-up occurs at low humidity, the issues it can cause in industrial and commercial situations, and how best to control it through humidification of the indoor environment.
Dave comments, “Electrostatic build-up is much more prevalent as indoor relative humidity drops. This means it can be seasonal issue for manufacturers. Indoor humidity is lowest in the winter, so manufacturers can experience increased problems of materials sticking together, being repelled by each other, or even sparks resulting from electrostatic discharge, during the colder months. A very effective way of dealing with this is to raise the indoor humidity to around 45%RH.
“Studies have shown that at higher levels of indoor humidity, the static charge caused by activities, such as walking across synthetic carpets, can be reduced by as much as 95-98%. This short podcast explains why and how manufacturers and facility managers can use humidity control as an effective anti-static measure.”

The podcast is available all major podcast channels, including Soundcloud, Spotify and Google Podcast by searching for “Condair” and also on the Condair website at www.condair.co.uk/podcast.

Crittall’s window display
Story
A town centre shopping mall in Stroud, Gloucestershire, has been given a new lease of life with Crittall playing a significant role in the makeover.
Dransfield Properties opted for a complete transformation of the Five Valleys Shopping Centre to include new retail outlets, as well as enhanced car parking, office space and a community hub with library.
Key to the interior appeal was replacing a jumble of disparate shopfronts and signage with a more ordered, modern appearance. Sheffield-based Dixon Dawson Architects selected Crittall W20 steel profiles for the task.
“The client wanted a particular style of glazing. I was familiar with Crittall and saw it as the best solution,” said Guy Dixon Dawson. “The whole mall was remodelled; frankly it was a bit of a mess beforehand. Now, everything, ceiling to floor, has been upgraded.”
The result is a simplified approach with Crittall’s slender steel profiled windows and doors providing a uniform appearance. All the cold form doors were a mix of hinged and automatic sliders.
