What are the differences between M&M Systems’ microprocessor based control systems and a PLC based control system? M&M Systems uses microprocessor based technology to produce a cost effective turn key solution to meet our customer’s control system needs. An excellent overview of the differences of our system compared to PLC based system is detailed in the document, PLC Myths and Realities. How does M&M Systems ensure that a control system meets the customer’s requirements and is fully functional when it leaves our facility? All custom control systems are first detailed in a specification which is provided to the customer for review and approval prior to any custom design work being completed. All products, custom or standard, also must complete full functional testing and burn-in before they are released for shipment. A good overview of our testing procedures is detailed in the Control System Software Testing Approach. How does M&M Systems achieve significant energy cost savings in Industrial Refrigeration Control applications? The first step in reducing energy cost is to understand how the energy bill is structured at the customer’s facility. Once this analysis is performed the next step is to understand the plant operation and equipment configuration to allow development of a plan which will reduce energy cost while maintaining product quality. A good overview of our approach is detailed in the presentation, Energy Savings. How does a user maintain secure access to our control systems and prevent unauthorized use or configuration changes? All M&M Systems control systems include an extensive password control function which allows levels of access to be defined on a per user basis. This permits our customers to maintain the level of user access they wish to have based on their operational requirements. Additional access information is provided by the system as it logs all user logins by date and time. Does the PC software support Windows 2000 and XP operating system? All PC software delivered after 2002 is fully compliant with Windows 2000 and XP operating systems. For older versions of the PC software we offer a PC Monitor 32-Bit Patch to upgrade your software for these versions of Windows. How does M&M Systems support preventative maintenance requirements in large industrial applications? For larger installations M&M Systems offers a PC software add-on called Maintenance Manager. This product allows the user to define maintenance schedules based on equipment run time and/or calendar time. The software continually monitors equipment runtime and will allow the operator to forecast what maintenance is required on a weekly, monthly or annual basis. What are the exposure effects of Ammonia (NH3)? Ammonia is a corrosive, colorless, gas with a sharp odor. Refrigerant grade anhydrous ammonia is clear free from visible impurities. It is at least 99.95 percent pure ammonia. Anhydrous ammonia gas is considerably lighter than air and will rise in dry air. However, because of ammonia's tremendous affinity for water, it reacts immediately with the humidity in the air and may remain close to the ground. Download PDF Ammonia (NH3) FAQ Sheet.

These may include headaches, dizziness, restlessness, a tingling or pins or needles feeling, difficulty breathing, sweating, tiredness, increased heart rate, elevated blood pressure, coma, asphyxia to convulsions and even frostbite if exposed to dry ice.
