Loss of moisture during storage is an important parameter that partly determines the storage time and quality of vegetables and fruit. An example: Europe is the largest producer of pears after China, and the Netherlands is the second largest European producer with 16% of the market after Italy (31%). The pear acreage in…
Solution for fire hazard from vacuum pumps
The vacuum pump of a VSA or VPSA nitrogen generator is a potentially fire hazard because the oil in it can get too hot. This has manifested itself numerous times over the years in engine room fires, or worse. Blue Atmosphere has a unique, standard protection that switches off the generator at temperatures…
Success through the right partner
We owe a lot to Blue Ocean Xlerator (www.boxnv.nl) in Wageningen. They are an important partner during the start-up of Blue Atmosphere. BOX is a private incubator/accelerator of and for entrepreneurs who invest in sustainable innovations. BOX and its research company TOP have many years of expertise in the field of Controlled Atmosphere…
Gastightening materials
Unfortunately, the conditioning of Controlled Atmosphere rooms does not depend solely on the conditioning machinery you use. Its basis is and remains the gastightness of rooms. An important factor in the finishing of CA rooms are the gastightening materials. It is about a special coating consisting of several layers that hermetically seal panel…
Gastight coating for CA rooms
GT-COAT is our ready-to-use elastomer-based coating for the gastight finishing of cold store panels. It is an acrylic, water-based, one-component sealant for wall and ceilings seams. GT-COAT can be applied with a roller, brush or airless spray gun. Substrates should be pre-treated with GT-PRIMER. Send your requirements to info@blueatmosphere.nl. Samples (including GT-FLEECE) for…
Use the right oil
VPSA nitrogen generators work with an oil-free blower. Partly for this reason, these machines have a very long life: the absorbent can never become contaminated with oil residues. However, the machine’s vacuum pump is oil-lubricated. These pumps require a special type of oil, however, this is not always taken seriously. Be careful though,…
The disadvantages of using cheap adsorber ventilators
Almost all adsorbers today are equipped with relatively inexpensive, direct-driven fans. Direct-drive sounds good, of course, and their power consumption is even lower too. If only it were so simple… For an adsorber to work optimally, a certain contact time is required; the residence time during which the air stream comes into contact…
Cheap can be expensive in the end
Because the pneumatic angle seat valves in a nitrogen generator often open and close, their quality is very important. We come across an increasing number of cheap valves in the market, which are not suitable. It often happens that we, or one of our partners, have to replace these valves, sometimes already after…
Fire hazard
VPSAs are usually the most efficient nitrogen generators for the storage of fresh products. They use an oil-free blower to bind oxygen to activated carbon (CMS). As a result, the CMS can never become contaminated with oil residues, as with a PSA. During regeneration, the CMS is cleaned with a vacuum pump. For…
