DEG: TWO DRYERS IN ONE, HIGHEST ENERGY ERGY SAVINGS AND MAXIMUM RELIABILITY

Transcription

1 : TWO RYRS IN ON, HIHST NRY RY SVINS N MXIMUM RLIILITY The patented lobal Transfer System (TS) technology of MT s line of refrigeration compressed air dryers offers 2 dryers in 1, with the dual advantages of direct expansion cooling at full load N energy-saving thermal storage operation at part load conditions. Unlike liquid-based cycling dryers, the TS dry mass requires no energy consuming circulation pump, so part load energy savings are maximized. TS allows the use of uncomplicated refrigeration and control systems, ensuring highest reliability and ease of use. automatically responds to changes in load, always providing maximum performance with minimum energy usage, without the need for any operator adjustments. : 2 dryers in 1, twice the benefits. onsistent ewpoints ven at low air flows User & nvironmentally riendly Large apacity Small ootprint Zero-Loss rain More energy savings Unlike a centrifugal separator that requires a minimum air velocity to insure droplet separation, s stainless steel demister separator efficiently removes condensed moisture even at low and medium air flows. Simple ON-O control of the refrigeration system and easy to use controls make the dryer user friendly. Non-ozonedepleting R-134a refrigerant, non-toxic silica mass and no risk of cross-contamination between the refrigerant and air circuits make environmental impact a non-issue. features the most compact thermal storage unit on the market. The extended surface heat exchanger with precooler/ reheater (0030 and larger) increases efficiency, whilst the special insulation reduces off cycle heat gains. The intelligent, zero-loss drain (standard from 0200, optional for smaller models) uses capacitive sensors to discharge only when condensate is present. This feature increases the dryer s ability to save energy by eliminating compressed air losses. ooling, conditioning, purifying.

2 Standard controls carefully designed to match the application The asyard controller is specially designed for the smaller dryers (0020 through 0200) to deliver key operating information and to provide the required functionality without over complication. The asyard offers the following features: User-adjustable dewpoint control; User-adjustable condensate drain control (either time-based or for zero-loss drain operation); L (green) indication of power on and of the energy saving operating mode; L (red) indication of high dewpoint and control board or sensor failures; Manual drain test button; Programmable alarms and set points. Reduced and simplified servicing Hinged, tilt-down control panel doors (0250 and larger) allow easy access to all electrical components. ll models feature interlocking, non-structural panels that are easily removed for complete internal access. The TS technology reduces the number of parts requiring servicing. uaranteed operation in all conditions allows operation up to 158 * inlet, 115 * ambient, and 232 psig working pressure. Together with a top mounted condenser (for reduced fouling) and the simplified refrigeration circuit, this ensures operates faultlessly in all conditions. (* values for differ) The Total ry ontrol (T) controller is a stateof-the-art, microprocessor-based user interface designed to provide all of the features needed to allow effortless operation on the larger models (0250 and above). The T controller offers the following features: Menu-driven programming capability with password protection for easy parameter adjustment and security; igital display of both dewpoint and air entering temperatures for quick verification of performance; Icon display of compressor operation and alarm conditions; oded alarm displays and an alarm history function that makes troubleshooting easy; ry contact for remote alarm signaling; igital input for remote on/off control; Serial port for connection of the dryer to a remote monitoring system (RS485/MOUS).

4 The TS principle TS benefits Unparalleled energy savings TS continuously matches dryer capacity to the load, providing energy savings of up to 80% in typical operating conditions. Simple & reliable like a household refrigerator, the TS uses an uncomplicated cooling circuit that is time-tested to provide trouble-free operation. onstant dewpoint sudden load variations are easily smoothed out by the thermal storage of the TS. Quick startup with TS there is no need to wait for a cool down period before applying load. ontinuous operation once your dryer is started, there is no need to turn it off the TS will continuously monitor the load and perform accordingly, with no energy consuming pump. Long service life without the need for a hot gas bypass to control its capacity, the refrigerant compressor runs cooler and less often, thereby extending the service life of your dryer. Seasonal savings Operational savings TS Provides Savings in Two Ways: normal dryer normal dryer summer mid-season winter 100% 60% % air flow 20% Seasonal Savings dryers must be selected to meet the most demanding loads, but most of the time the actual load is much lower. y matching dryer capacity to the actual load, can reduce energy usage by an average of 27%. Operational Savings no compressed air system operates at full capacity all of the time; 's energy consumption is automatically and reliably reduced in all partial load conditions. compressed air alluminium fins refrigerant silica mass exchange through fins exchange through fins and mass exchange through mass T S : M a j o r n e r g y S a v i n g s w i t h N o M o v i n g Pa r t s The unique TS exchanger's compressed air tubes and refrigerant tubes are encased in a bed of silica mass. luminium fins connect the air and refrigerant tubes together. onsequently heat transfers from the compressed air to the refrigerant both directly through the fins, and indirectly through the silica. ull Load (maximum operating conditions) The compressed air is cooled directly through the aluminum fins. In this condition, since heat does not have to travel through the mass, efficiency is maximized. The silica actually provides insulation from ambient heat gain. Partial Load (typical conditions) Since the refrigeration capacity is greater than the load, the excess capacity cools the silica mass. The compressed air is then cooled by the mass, allowing simple compressor cycling to closely match the load. Zero Load (stand-by conditions) Since there is no compressed air load, the dryer s refrigeration system only operates to maintain the thermal mass at design temperature. The result is automatic capacity turndown with immediate restart capability.
