<strong>MPS</strong> Chiller Package<br />
The <strong>MPS</strong> Chiller Package incorporates plate and shell heat exchanger technology with a split-flow surge drum and state of the art<br />
liquid level controls into a <strong>com</strong>plete package which reduces installation time and cost when <strong>com</strong>pared to field fabricated units.<br />
The <strong>MPS</strong> Chiller Package ships <strong>com</strong>plete with an oil management system and proportional liquid feed assembly requiring only<br />
two refrigerant connections in the field.<br />
Typical Applications<br />
• Chilled water and glycol solutions for use in<br />
process cooling and air conditoning<br />
• NH3/CO2 Cascade Condenser<br />
• NH3 Sub-cooler<br />

Liquid Level Column<br />
• Level indicating<br />
column with RVS<br />
electronic level probe<br />
• High level shutdown<br />
float switch for<br />
<strong>com</strong>pressor<br />
protection<br />
Proportional Liquid Feed Assembly<br />
• Modulating valve minimizes vessel<br />
pressure surges and liquid line hammer<br />
• Backup solenoid valve or UPS<br />
(uninterrupted power supply) provides<br />
positive shutoff in the event of a power<br />
failure<br />
Matrix LLC Control<br />
• Reads 4-20mA signal from level probe and provides visual readout in digital and color bar graph form on panel.<br />
• Adjustable high and low level alarms and cut outs.<br />
• Door-mounted (7) button keypad. No need to open enclosure to change settings.<br />
• Communications via industry standard protocol MODBUS-RTU over RS-485.<br />
• Factory mounted and wired requiring only a single power connection in the field.<br />
<strong>Plate</strong> & <strong>Shell</strong> Heat Exchanger<br />
• High efficiency with low refrigerant charge<br />
• Elimination of gaskets means<br />
• No gasket leaks<br />
• No expensive gasket maintenance<br />
• No elastomer in<strong>com</strong>patibility problems with process fluid<br />
• No gasket limitation of pressure or temperature<br />

Horizontal Surge<br />
Drum with Dual<br />
Relief Assembly<br />
• Split-flow design to<br />
reduce overall size<br />
• Stainless steel<br />
nameplate bracket<br />
and standoff to<br />
prevent corrosion<br />
Options<br />
• Multiple heat exchangers may be incorporated into a single<br />
package for higher process fluid flow rates and capacity<br />
• Package may be designed with connections and space for<br />
additional heat exchanger to handle future expansion<br />
• Conventional on/off solenoid and hand expansion valve<br />
liquid feed assemblies (single or dual)<br />
• Temperature controlled suction pressure regulator<br />
• Seismic design<br />
• Post weld heat treatment
