“How do exhaust systems for biology labs work?”
Chemical fume hoods are vital for exhausting noxious fumes from scientific labs. However, biology labs have needs that are more sensitive. Since they are dealing with live organisms, fumes from their lab spaces cannot mix with others and exhaust air will need to be more filtered. For this reason, Specially designed Biosafety Cabinets will have to be used.

Ductless Fume Hoods
“How can we have a fume hood without ducts?”
Fume hoods are well known for their ducts. However, is it possible to have fume hoods without ducts? Well, with Ductless Fume Hoods, we can suck up chemical fumes from all over the workplace and filter it out into the atmosphere.

VAV Fume Hoods
“How can we make fume hoods better performing?”
Fume hoods are a vital component for any scientific lab. Without them dangerous fumes would not be able to be ventilated away and people working in the lab could have their lives at stake. When common solution is to implement a CAV fume hood. However, the fact that the air volume exchange rate does not vary leaves it with performance and energy inefficiencies. This can be solved by implementing VAV Fume Hoods (Variable Air Volume) which can change its air intake when needed. Labs that implement this often see great strides in performance and energy effectiveness.

“What are the simplest types of fume hoods?”
Fume hoods are used to take in fumes from chemical lab stations and ventilate them into the atmosphere. The simplest type is where the fume hood releases the same amount of air at a constant rate all the time, no matter what. These CAV Fume hoods (Constant Air Volume) are the simplest type of fume hoods available. The fact that they cannot change their air velocity in response to external stimuli means that they give sub-optimal performance.

Ducted Fume Hoods
“What is the most common type of fume hood?”
Fume hoods are a vital part of scientific labs. The most common type is usually a Ducted Fume Hood design where conditioned air is drawn from the lab space and siphoned into the outside atmosphere. The simplicity of the design has made it a staple of labs across the world.

“How do scientists ensure that they are safe from chemical fumes in the lab?”
Biology and Chemistry often involve a lot of messy lab work involving chemicals, which may give off dangerous vapors. To prevent these from damaging the air quality in the lab and the health of the denizens, the fumes must be cycled away. This is commonly done through fume hoods, which sucks in air from a workbench and ventilates it to the atmosphere. Fume hoods are a vital part of the safety of every lab and have become a staple of the wet-bench research environment.

Cooling Tower Water Treatment
“Why do we need to treat cooling tower water over time?”
Cooling towers are one of the lifelines to our civilization. It enables hydro-thermal systems to control their operation temperature and return to normal processes. However, if left unchecked overtime the water will become contaminated with bacteria which could impede the flow of water. For this reason, cooling towers need to undergo periodic water treatment. With Cooling Tower Water Treatment we can ensure the safety of our critical infrastructure.
