Baxi Commercial HeatingStand No. T40 at NEMEXNew renewable andsustainable productsunder both the AndrewsWater Heaters andPotterton Commercialbrands will be exhibitedfor the first time on theBaxi CommercialHeating Stand. The BaxiSenertec DACHS mini-CHP unit will also beon display at this event.Andrews Water HeatersAndrews Water Heaters, UK marketleader in commercial water heatingsolutions, has launched anevacuated tube solar collectoroption to complement theSOLARflo renewable energy waterheating package, as an alternativeto the currently offered glazed flatplate collectors. SOLARfloevacuated tube collectors areavailable in 20 or 30 tube optionswith gross collector areas of2.83m2 and 4.25m2 respectively.These supply heated water tosingle coil or twin coil unventedhot water cylinders holdingbetween 450 litres and 900 litres. Smaller andlarger bespoke solutions are also available.New evaporativehumidifierJS Humidifiers hasenhanced its reputationfor low energy humidifierswith the launch of theHumEvap MC3 evaporativehumidifier.Energy consumption is 150 timeslower than electric steamhumidifiers withcorrespondinglymassivereductions inCO2 emissions.The newhumidifier alsoincorporatesimproved controland innovativehygiene features.The HumEvap MC3 is locatedinside a duct or AHU and humidifiesby passing the air through a wettedfibre matrix. It is suitable for any sizeduct and can deliver huge volumes ofmoisture to an atmosphere with veryclose control and runs on just 500W.This is in contrast to a steam systemthat can consume up to 75kW toproduce an equivalent output. TheHumEvap MC3 also has the addedbenefit of providing up to 12 o Cevaporative cooling to the air beinghumidified, further reducing abuilding’s energy consumption andWhichever collectors are chosen, the SOLARflopackage is compatible with the innovative AndrewsMAXXflo, Queen’s Award winning condensingstainless steel direct fired storage waterheater. Designed for large residential,commercial and industrial applications, its highlyefficient stainless steel heat exchanger, specialburners and tank design, enable high performance,low energy consumption and low running costs to becombined with low carbon dioxideand nitrogen oxide emissions.Commercial heating specialistPotterton Commercial is showcasingan exciting new product and the firstin their developing range ofrenewable low carbon solutions.This 21.3kW ground source heatpump is aimed at commercialproperties and is supplied as apackage to include heat pump,ground loop manifold and sourcesidepump station. It has one of thehighest Coefficient of Performance(COP)available on the market, whichis 4.7 based on 0°C sourcetemperature and 35°C loadtemperature and a whisper quietnoise level of 33dB(A) at 1 metre. The latestEurocondense two range from Potterton Commercialis a perfect choice for applications where highoutputs are required.

Unlike UV light sterilisation,it does not require a power source andthere is no risk ofbacteria being“shadowed” byparticles in thewater or bacteriaforming as theUV bulbs reducein intensity. ThePureFlo Ag~ usesnewly developedAgentosan technology,which selfregulates theamount of silver ions that are releasedinto a water system and preventsover-dosing.The humidification system is the onlyone of its kind to have obtained bothWRAS and the VDI 6022(D) RLTHygiene certification.The control panel on the HumEvapMC3 can be situated up to 100m awayfrom the evaporative module. It iscompact in size and gives digitalcontrol over desired relative humidityand temperature levels of the airleaving the matrix.Reader Reply No.: 111071h.v.a.c.Two new energyefficient productsfrom Zip HeatersZip Heaters (UK) Ltd isdelighted to announce thelaunch of two newappliances for thecommercial market; the ZipDuo and the new andimproved ZipHydroboilPlus.New andimprovedHydroboil Plus:This wallmounted instantboiling waterheater is a topof the range, highperformanceproduct raisingthe energysavings benchmark. Available in threemodels, three, five and seven and ahalf litres, in either stainless steel orwhite powder coated casing, theHydroboil Plus provides instant boilingwater for beverages and cooking.Delivering water within 1˚C of boilingpoint, via an ergonomically designedcool-touch tap, the appliance deliversup to 45 cups of boiling water at anyone time, with a recovery rate of up to140 cups per hour. The HydroboilAirbloc keeps thefreshness in at AsdaAirbloc air curtains are proving aneffective barrier against flying insectsand prevailing winds at Asda’s newdistribution depot at Chepstow. As aresult, food stored in the warehouse canbe kept fresher and air temperaturesmaintained.The supermarket giant’s 45,000m 2 facility has nine 4mhigh loading bay doors, each between 3.5 and 4mwide. The doors are in constant use during the 24-hour operation of the warehouse.Such a large space building is expensive to heat tothe required constant 15°C. Asda wants to ensureeconomies are maintained within its facilities and hasused air curtains effectively in other large premises forheat protection.The Chepstow depot deploys Airbloc AB ambient aircurtains positioned vertically beside each of theloading bay doors. The air curtains deliver a sheet ofcold air at critical velocity across each doorway. Thisprovides sufficient air turbulence to prevent flyinginsects from crossing into the building. Winds atspeeds of up to 11mph are also effectively excluded.In most buildings, air curtains are installed horizontallyabove a doorway. Reader Reply No.: 112054Plus also features a light sensor whichallows the appliance to automaticallyinterlock within a buildingmanagement lighting system; whenthe lights in the building are turned off,the sensor detects this and theappliance switches toenergy save mode,allowing thetemperature of thewater to drop and bemaintained at 65˚C.Zip Duo: This wallhung and countermounted instant boilingand chilled filteredwater system isavailable in two models,five or 15 litres.Available also in eitherstainless steel or whitepowder coated casing, the Zip Duo isideal for cafés, restaurants andoffices, where it is installed as a backof house appliance.
