WORLDWIDE LEADER IN THE STUDY DESIGN AND PRODUCTION OF FUME HOODS

This is ASEM® this is the Quality this is the Certification CERTIFICATION = SAFETY Certification is the guarante of compliance with the SAFETY objective that we give all our Customers through our products. SAFETY to guarantee health without compromise. EXPERIENCE 50 years in the industry have let ASEM® acquire a technical background that can provide all-round solutions. QUALITY The countless supplies we have provided to the most important industries, universities, hospitals and research centres, in Italy and abroad, confirm a consensus on quality that endures over time. TECHNOLOGY Constant research...

BACKGROUND NOTES AND REMARKS ON THE IMPORTANCE OF THE HOOD IN THE LABORATORY The first hood was invented in 1450 by an Italian, who was called Giuliano Sorboni and was a student of Lucrezia Borgia, or rather her assistant, and who used arsenic on the noble lady’s orders for reasons we all know. In order to avoid “self-poisoning” during the preparation phase, and in the absence of the mechanical components that appeared thanks to the arrival of electricity a few centuries later, Sorboni had to design a fairly basic but equally effective protection device. In effect, by preparing the potions with...

ASEM® FUME HOODS The ASEM® total expulsion laboratory fume extraction hoods ensure protection of the operator when handling toxic products, while maintaining a work environment that meets safety requirements (Legislative Decree 81/08). The accurate design and construction allow significantly better performance than what is required by EN standards. The hoods are available with different front sizes 120, 150, 180, 210 and 240 cm, versions in different materials with standard worktop 90 cm from the ground; for distillation with worktop height 50 cm; walk-in for working with cumbersome and heavy...

8. ECONOMY FLOW (LOW CONSUMPTION LOCK) 7. AIR-FOIL ARMREST WITH ANEMOMETRIC PROBE 6. HORIZONTALLY SLIDING WINDOWS 1. AIRFOIL Elements that promote the entry of air inside the hood, avoiding the formation of vortices that could disrupt the flow, and helping to avoid dead spots where vapours could stagnate. SAFETY to guarantee health without compromise.. 2. DOUBLE EXTRACTION As a double base, it promotes elimination of heavy vapours by increasing the extraction speed from the back. Easy to remove, it makes it possible to "sanitise" the rear part from any sludge and hazardous dust, as required by...

6. HORIZONTALLY SLIDING GLASS Glass sections that can be opened horizontally allowing operation, with the sash lowered, in complete protection. 7. AIRFOIL (ARMREST WITH ANEMOMETRIC PROBE) 3. ALARM Monitoring system for good suction operation. In the event of low flow, a buzzer and an LED will sound and flash to get the operator’s attention when the “containment” conditions are not being ensured. The anemometric probe is normally positioned on the roof of the hood. This position involves some problems over time: a) Possible dust deposit. b) Interference due to the temperature of the hot air in...

THE QUALITY IS THE CERTAINTY OF THE CERTIFICATION Hoods must be considered proper safety devices as they must guarantee the health of those who work inside the Laboratory. The objective of ASEM® is obsessive research to reduce risks to operators to zero. INNER TEST All ASEM® fume hoods are certified by an accredited body and then tested according to EN 14175 standards. All our test instruments are also subject to periodic checks and calibrations. OUTER TEST This is ASEM® this is the Quality this is the Certification ASEM FUME CABINETS

ELECTRICAL TESTS SMOKE TEST TESTS WITH LIGHT METER TESTS WITH DYNAMOMETER All electrical components are tested according to EN 61010-1 CEI 66-5 standards. Every six months a certification body checks all production processes to ensure that all hoods conform to the original product. Each of our hoods is equipped with a serial number for the traceability of the “dossier” where the production processes are stored; this allows us to guarantee the supply of spare parts and assistance over time. All ASEM® hoods come with an instruction booklet with a report of the tests carried out and the relative...

NEW GENERATION OF SUCTION FUME HOODS ASEM® DPC2 WITH VAV (RMP)AND BALANCED DOUBLE SUCTION WITH AND WITHOUT DOUBLE MOTOR The only VAV system with a certified response time of 0.5 seconds. With VAV (RMP) and balanced double suction, with and without double motor. The total extraction fume hoods are normally provided with “double suction” obtained by a rear panel which, connected to the roof, increases the speed in its “cavity”, promoting the extraction of heavy stagnant vapours on the worktop. ASEM DPC2 VIDEO

The patented DPC2 system consists of suction in the lower part, and potentially on the sides of a total extraction fume hood, done mechanically by a remote motor-driven fan. This suction will act concurrently with the main suction, and can be adjusted manually or automatically by means of a frequency variator. With the glass raised, it will give greater preference and extraction air flow to the main motor. With the glass lowered, it will give preference and extraction air flow to the lower motor. C In the diagram you can see, with the blue line, the trend of the classic variable flow (VAV) with...

THE ADVANTAGES OF THE DOUBLE SUCTION SYSTEM The advantages of the system are a reduction in the required flow rates, a homogeneous suction that avoids turbulence, the possibility to increase or decrease the suction according to the needs of the operator and the type of product being handled. This system avoids the problem created by the classic VAV (variable volume) system which, once the sash has been lowered, keeping the suction speed constant, drastically reduces the volume of air flow so it is no longer sufficient to guarantee “washing”, especially when the interior uses bunsens, sand baths...
