Watlow PM controllers
What is the difference between model numbers ending in BAA and models ending in AAA?
Both controllers have the same form, fit, and function in fact they are the same controller with the exception of the program menus. The PM controllers ending in BAA have a more user-friendly EXPRESS menu that is application-oriented for thermal control. The PM controllers ending in AAA have a more comprehensive menu that in addition to thermal control the programming of various other processes such as pressure, humidity, valve control and much more is included in the programing menu.

What is the difference between model numbers beginning with the letter B or A after the first dash?
The 1/16th DIN Watlow EZ-Zone PM controllers beginning with the letter B after the first dash have blue tooth communication capability. The blue tooth is user selected on or off and there is no extra charge for this feature. Blue tooth allows viewing or programing the controller via a smart phone or blue tooth enabled pad using Watlow's EZ-Link software available free from Apple's app/store or the Google/play store. The 1/16th DIN Watlow EZ-Zone PM controllers beginning with the letter A after the first dash have standard serial bus capability allowing RS-485 2-wire to USB communication using the same Watlow EZ-Link free software together with a serial to USB accessory connector purchased seperatly.

Airmaster Fans
I am looking for the most energy efficient fans. Would a fan with a lower horse power be more energy efficient?
All things being equal such as same motor RPM, Voltage, Service-Factor and Insulation: Yes a lower HP motor consumes less energy, the efficiency would depend on the CFM produced for the motor size.

Is a higher CFM or lower CFM more energy efficient?
The CFM is determined by the size and shape of the fan blade in conjunction with the RPM of the motor.  That being said, the actual energy efficiency would be determined by dividing the CFM by the energy being used to produce the CFM. A good rule of thumb would be to divide the CFM by the wattage the motor uses.

I am comparing a fan with a 1/2-HP motor producing 6700/9250-cfm and your Airmaster DJ-PF30-2SPJ-DC. Which is the more efficient?
The Airmaster DJ-PF30-2SPJ-DC uses a 1/3-HP motor and produces 6915/5000-cfm.  Based on the airmaster motor HP consuming 310-watts the 6915/cfm equates to 22.31/cfm per watt consumed. and the fan with the 1/2-HP motor consuming 1130-watts the 9250/cfm equates to 8.19/cfm per watt consumed.  The more CFM per watt consumed is the more efficient, illustrating the Airmaster is the more efficient.

Slide mold release agents
What is NSF category M1?
NSF M1 is a classification of registered mold release agents that have passed a thorough toxicology assessment and are considered acceptable for use on molds and will not adhere to the finished products that that may come in contact with food.

What mold release agents are registered as NSF category M1?
Slide 41612N EconoMIST food-grade lubricant
Slide 42112N silicone spray lube food approved

What is NSF category H1?
Lubricants that are registered as acceptable for use in and around food processing areas.
The lubricant is formulated for incidental food contact and can be used as a protective anti-rust film, a mold release agent or for lubricating machine parts or equipment that have the potential for exposure to food.
