2 Cress Manufacturing Company Inc., Is a leader in the industry of manufacture of electric furnaces. We are an organization that provides services and goods for the heat treating industry. Our goal is to achieve an excellent product to satisfy the needs and requirements of our customers. Cress was founded in 1973, as a company with a simple concept to provide exceptionally high quality products and services. With this goal in mind, Cress has evolved into a very important manufacturer and distributor of heat treating furnaces, in the United States and many other countries. We manufacture, export and distribute heat treating furnaces for the metal industry, quartz glass, industrial ceramics, jewelry, porcelain, pottery, ornamental ceramics and many other applications. For our company, innovation is essential to transform a good idea into a product or service of high value to our customers. We can adapt to the needs of our customers; therefore, if you have something in mind we can build it for you. With these ideas in mind, we strive to provide better services and products that will last and provide years of service. Furnace Selection Our industrial furnaces can be classified as one of two basic types, Heat Treating Furnaces also known as hardening furnaces and Draw Furnaces also known as annealing, tempering or forced convection furnaces. Heat treat (Hardening) furnaces have higher heat output power than draw furnaces due to the elevated temperatures at which they operate. Heat transfer to the tool steel is accomplished by a very efficient process called direct radiation. Temperature uniformity in these furnaces is best in the red heat range. Normal maximum temperature is 2250 F (1232 C). Optional 2400 F (1316 C) maximum temperature versions are available. Draw furnaces are used for tempering and other low temperature processes. They normally operate at temperatures below red heat range where heat transfer to the tool steel is accomplished by the process of convection heat transfer. To increase convection efficiency, these furnaces are equipped with a fan in the heating chamber to move air (Forced Convection). This delivers a temperature uniformity of ± 10 F (± 6 C) or better. Maximum temperature is 1250 F (677 C). Optional 2000 F (1093 C) maximum temperature versions are available. Heat treating processes consist of two basic steps, hardening and tempering. Hardening processes occur at high temperatures that are well into the red heat range. Drawing, tempering and annealing processes normally occur at temperatures below red heat range. When a part is hardened, it is heated to a high temperature, held there for a required time period, then removed from the furnace to be quenched (Cooled). This is usually accomplished by submerging the part into a liquid quenching material or by placing the part on a cooling rack in still air. The part should only be cooled to about 150 F (66 C), and then placed into a furnace at the tempering temperature. Due to the heat treat furnace not being able to cool as fast as the part, it is best to have a separate furnace for each step of the process. 2 Cress Manufacturing Company Inc Convair Drive Carson City, Nevada

3 Digital Temperature Control Selection Digital temperature controls fall into two basic types, process controllers and high limit controls (over temperature controls). Process Controls handle the temperature and time requirements of the heat treat processes. These controls come in two types, non-programmable (single set point) and programmable. Non-Programmable controls such as the model PM3E are a single set point control, you simply input the desired temperature. The furnace heats to the desired temperature as fast as possible. The furnace will stay at the set temperature until changed or turned off. This is the least expensive standard control. Programmable Controls such as the models PM4R and the F4H allow the heat up rate to be controlled, temperature can be ramped down as well as ramped up, multi-step heat treating can be input as a single process, your heat treat process programs can be stored in the controls memory for easy and accurate repeatability. In manual mode (non-program) operation, the controls work the same as the model PM3E. High Limit Controls such as the model LV help protect the furnace and your load in the case of a failure in the primary (process) control or other related primary control loop components. The high limit control loop is completely independent of the primary control loop. The programmable process controls are available with an optional audible alarm feature, which can signal desired process points and end of process. A data communications option is also available, which allows full control interface with a computer. STANDARD WATLOW PM4R CONTROL FOUR 10 STEP PROGRAM MEMORY FILES Microprocessor-based, ¼ DIN programmable ramping control providing four, 10 step program memory fizles, or easy to use non-ramping set point operation. The PM4 is designed to operate in the most demanding industrial environments. Interface: membrane Front panel push buttons, dual LED displays WATLOW F4 CONTROL 250 STEP RAMPING CONTROL This microprocessor based ¼ DIN ramping control providing 250 steps of programmability within up to 40 nameable profiles. Control over broad temperature ranges using the four sets of PID parameters. Interface: Membrane front panel, single four digit LED s with second four line LCD display. ECONOMY WATLOW PM3E CONTROL Microprocessor based single set-point control Interface: Membrane front panel, dual LED displays. OPTIONAL WATLOW LV HIGH LIMIT CONTROL (ADDITIONAL to primary control) This FM approved limit control is operated using a separate thermocouple. Mechanical relays break power to the elements when tripped. A High Limit Control gives added assurance at a small cost that the furnace and materials fired do not exceed the temperature indicated.
