Creepy Crawlies?

Do You Have Mad Scientists?

They’re fun Halloween costume ideas…Dr. Jekyl & Mr. Hyde, Lex Luthor, Doc Brown, and so many other rabidly driven scientists, eccentric engineers, crackpot inventors, or indefatigable innovators – they’re all great, but we want to know about your Mad Scientists.

Do you have actual scientists who are angry? …or are your “Mad Scientists” impulsive experimenters on the plant floor?

Whether your plant has upset scientists or an exuberant innovator on the floor (who is filled with unbridled passion to experiment and try new things) – Koss Industrial can help you optimize your process and work with your Mad Scientists.

…if your scientists are truly mad (…as in insane, unhinged, deranged, or just plain loopy), then you have our sympathies (and you should probably try to stay on their good side)!

Manage the Mad Scientist on your floor.

Prevent the “Mad Scientists” on the floor from following ineffective impulses and ideas – record & report chemical use.

You see it happening…again.

Your “Mr. Clean” has the best intentions…his logic appears to be:
“If I use a half gallon today, then a whole gallon tomorrow will work even better! Probably twice as fast!!”

Sound familiar? We know what happens. Adding more cleaning solution is rarely the answer. If we use twice as much detergent, our clothes aren’t twice as clean after washing, but your “Mr. Clean” doesn’t  believe that…and you’re buying twice as much chemical.

Whether you are making ice cream or you’re cleaning equipment – KOSS can help you work with your innovative, impulsive machine operator (a.k.a. Mad Scientist). Don’t stifle their creativity, control your innovator’s environment. You can even empower their experiments by monitoring, recording, and reporting the results. “Why was this batch bad? Why is this one better?” Give them the tools they need to succeed and protect your batches by controlling their “experiments.” Unlock the secrets of your Mad Scientist’s success – partner with Koss Industrial’s Electrical Dept. for chemical monitoring with controls. Automation, Controls, Reporting and more – trust us to optimize your Mad Scientist’s top-secret laboratory.

Appease your (literally) Mad Scientists.

If they’re literally unhappy or upset, we have a few ideas on how to help your scientists find happiness.

Scientists & Laboratories – okay, so we all agree that they go together like peanut butter & jelly, cheese & crackers, a DeLorean DMC-12 & time travel…so what’s our solution to keeping your scientists happy?  A totally wicked laboratory (wicked as in awesome, not wicked like witches). You can’t be a great Mad Scientist without an awesome Secret Laboratory.

Not quite ready to invest in lab-size equipment or plants? You could try appeasing your scientists with smaller gifts, trinkets and flowers; but Koss Industrial might still be able to help you. PLAN B, we recommend you try humor on your actually-angry Mad Scientists; maybe say something like “Don’t trust atoms…they make up everything.”  …unless you have a lot of employees named Adam, then that is probably not a good joke for you to be using in the workplace.

CPM Valves


CPM is an acronym for Constant-Pressure Modulating Valve. There are two types of CPM valves, -O (outlet) & -I (inlet). The CPM-O valves go before the separator (in place of a balance tank), and the CPM-I valves goes after the separator.

CPM-I Valves are more common. The I valve maintains a constant pressure in the process line at the the inlet side of the valve. Typical applications are after separators, heat exchangers, etc. and as overflow valves.

The CPMO maintains a constant pressure in the process line at the outlet side of the valve.


Typical application of CPMO valves are before filling/bottling machines, etc. The round bottom of the CPM valves means it is 3A. There is also a “-2″ after the I or O, to denote that it is sanitary.  CPM valves are typically 2”.

There is a “freak” 3″ CPM that was made by Alfa Laval – the CPM-I-D60 valve – this valve consists of upper and lower valve bodies, an inlet tube, a cover, a valve plug with diaphragm unit and clamps. The diaphragm unit consists of two flexible diaphragms supported by 12 stainless steel sectors between them.



These valves are remote-controlled by compressed air and operate without a transmitter in the product line and require only a pressure regulating valve for the compressed air and pressure gauge in the product line. A diaphragm/valve plug system reacts immediately to any alteration of the product pressure and changes position so that the preset pressure is maintained.

NOTE: The inlet valve opens at increasing product pressure and vice versa, while the outlet valves closes at increasing pressure and vice versa as well.

STANDARD DESIGN: CPM valves consist of a valve body w/ valve seat, cover, and a valve plug with a diaphragm unit and a clamp. The diaphragm unit consists of a stainless steel disc which is divided into sectors and of flexible diaphragms which are placed on each side of the sectors. The cover and the valve body are clamped together. The valve body and seat are welded together.

When sizing these valves pressure drop and flow are very important, you always want to get as near as possible to the 50% open curve when sizing these.
