5 Why we are the leaders 5 Maxi-Therm, the leaders in heat transfer technology At Maxi-Therm, we are at the forefront of innovation, developing industry-leading heat transfer technology that is more cost-effective, greener, and more energy and space efficient than conventional heat exchange systems. Our award-winning achievements Maxi-Therm s patented Vertical Flooded Heat Exchanger is industry-recognized, receiving honorable mention at the ASHRAE, AHR EXPO 2005, Orlando, Florida. Over the past 7 years, we have designed and built over 250 of our patented Vertical Flooded Heat Exchangers in hospital, institutional, pharmaceutical and also co- complexes, offering our clients an efficient, cost-effective heat transfer solution. First Prize For Product Design Technology 2002 A.Q.M.E. Canada.

8 Hot water Steam to liquid The Maxi-Therm concept We developed our patented, award-winning Vertical Flooded Heat Exchanger based on a proven system used in Europe for over 25 years but we innovated to enhance its performance. Like the European design, our Vertical Flooded Heat Exchanger features an oversized vertical shell & tube heat exchanger «A» that uses latent & sensible heat of steam to heat a liquid. Because it is oversized, the heat exchanger becomes flooded with condensate that is evacuated at a preset subcooled temperature (usually 200 F), making it possible to optimize use of the sensible heat of steam and eliminate the occurrence of flash steam. A condensate control valve «B» varies the level of condensate in the heat exchanger according to the process load «D & G» resulting in a 5.4% to 20% energy savings and reduction of greenhouse gas. 8 Maxi-Therm s patented innovations When developing our system, we identified two major issues with the European system: 1. The steam pressure must always be lower than the liquid pressure. 2. There is no guarantee of stability of the heated liquid outlet set point temperature, which results in a high level of wasted energy, thereby compromising cost-effectiveness. With Maxi-Therm s patented design, however, we resolved these issues 1. No pressure reducing station on the steam side «C» and no safety relief valve(s) to the roof are required. In fact, we recommend using high-pressure steam (even over 170 psig and we always size the heat exchanger to subcool condensate to 200 F «D». Plus, our heat exchanger uses more sensible heat, for greater performance and efficiency. Simply, our technology always uses ± 1000 btu/lb. of total heat of steam, either at 10 psig or 125 psig steam pressure. 2. We have achieved stability of heated liquid outlet set point temperature for building heat «H». In fact, we are the first to guarantee ± 2 F of set point temperature, even when variable speed drives are used on the circulating pump «G». 3. Stabilizing pump «J» pre-heats incoming liquid and creates additional turbulence in heat exchanger «A», averaging temperature towards sensor «D». Therefore the purpose of the stabilization circuit is to stabilize the fluid temperature across the heat exchanger circuit. 4. No condensate pumping substation needed to lift condensate «E». 5. Condensate Mixer «F» enables high pressure steam traps «I» to discharge directly in the flooded return line «E» without creating any water hammer. Online catalog maxi-therm.net

10 Hot water Steam to liquid Conventional Control (1) (4) (3) (6) 10 (8) (4) (2) (5) (1) Less Make-up Water The boiler gets back more condensate so you use less fresh water. This also means less softening, chemical treatment, and surface blowdown. (2) Condensate Pumps Last Longer Condensate that is too hot causes pump cavitation and seal leaks. (3) No STEAM PRV STATION The Maxi-Therm can use high, medium or low pressure steam directly. (4) NO STEAM SAFETY RELIEF TO ROOF Many times the vent piping is the most expensive part of the entire system. Maxi-Therm can eliminate the need for both the pressure relief and condensate receiver vent. Online catalog maxi-therm.net

The pump will require electricity or steam power, again using more energy. This power source will need a control system and isolation. (6) Smaller Steam Inlet And condensate return lines (7) Smaller CONTROL Valve (8) Vacuum Breaker The Maxi-Therm runs at constant pressure and a vacuum breaker is not needed. Independent site testing demonstrated seven times less corrosion rate.

22 Steam to steam Clean steam The Maxi-Therm CS Series makes clean steam if used with softened or demineralized water (D.I., R.O.). Using central or district steam, Maxi-Therm will make steam at pressures above 0 psig. Maxi-Therm may consume 15.4% LESS steam than generators on central plant steam. The units are pre-assembled and tested. 22 Maxi-Therm CS units can be used for Humidification Sterilization - 97% saturated Direct steam cleaning Principle of operation High pressure steam flows through a CONTROL VALVE, and is throttled to maintain the CLEAN STEAM OUT pressure. Clean steam is generated by the HEAT EXCHANGER vessel. The vertical design uses a second RESERVE vessel, for separation, plus level and pressure stabilization. Incoming water flows through two PRE-HEATER units. One removes heat from the blowdown water, the other cools hot condensate draining from the HEAT EXCHANGER coil. If sudden pressure fluctuations are expected, typical of autoclave applications, an optional BACK PRESSURE VALVE can be furnished. This keeps the outlet steam dry. The AUTOMATIC FEED WATER VALVE and BLOW DOWN VALVE are controlled together. This enables the heating of the feed water. Sterilization Maxi-Therm can supply quality steam to 97% saturated and greater (less than 3% of the mixture mass is liquid). As recommended by sterilizer manufacturers and also clearly indicated in the manual Sterilization technology for the healthcare facility, second edition, MariMargaret Reichert and Jack H. Young.
