DSD Series Direct Drive Kaeser Rotary Screw Compressor

Standard Compressor Package Includes:

COMPRESSOR:  Single-stage, flooded, rotary screw airend with the power-saving, proprietary SIGMA Profile delivers pressures up to 217psig.

ELECTRIC MOTOR:  TEFC, 460V, 3-phase, 60Hz, 3600rpm, class F insulation, and EISA compliant.  Other voltages are available, as well as 50Hz.  Consult factory for pricing.

STARTER:  Magnetic Wye-Delta reduced voltage starter ensures low starting current and smooth acceleration

ONE-TO-ONE DIRECT DRIVER:  1 to 1 direct drive with maintenance-free coupling provides maximum transmission efficiency.

SIGMA CONTROL 2™ SYSTEM:  This intelligent controller comes standard with multiple pre-programmed control profiles so you can select the one that best fits your application.  SIGMA Control 2 monitors more than 20 critical operating parameters, shuts the unit down to prevent damage and signals if immediate service is required.  It also tracks preventive maintenance intervals and provides notice when PMs are due.  SIGMA Control 2 has superior communications capabilities.  An Ethernet port and built-in web-server enable remote access and seamless integration into plant control/monitoring systems.  ModBuc, Profibus and other industrial communication interfaces are also available as plug in options. 

AIR COOLING SYSTEM:  Three separate cooling air inlet zones for the aftercooler, compressor, and drive motor ensure optimum cooling.  Drawing ambient air across the coolers and motor through separate zones avoids preheating and results in lower approach temperatures, longer lubricant life, and cooler motor temperatures.  Two-stage, 1 micron air intake filter.  Replaceable, cleanable cartridge extends fluid drain intervals and airend life.  Pneumatic inlet and vent valve are included.  Combined reservoir and separator tank with 3-stage separation system ensures minimal fluid carry over 2 ppm or less (by weight).  Quick-change devices on the separator and cooler allow complete, fast, and easy fluid changes.  ASME separator tank is equipped with quick-disconnect fittings for manual versification of separator element contamination.  Combination valve incorporates a thermostatically controlled valve, cooler by-pass and micro fluid filter.  The thermostatically controlled valve ensures perfect fluid temperature regulation.  The micro fluid filter utilizes a spin-on cartridge.  Main air lines are made of pipe and incorporate flexible pipe connections.  High efficiency coolers are included.  Standard units are air-cooled, optional water cooling is available. Radial cooling fan reduces package noise and produces greater static pressure across the coolers.  Includes moisture separator and Eco-Drain after the air aftercooler.  Variable speed controlled fan on the fluid cooler in addition to single speed radial fanon the air cooler from models CSD 100/125.

WATER COOLED VERSION:  Water-cooled version with standard coolers is available at no extra charge (Cooling Water Throttling Valve is available with extra charge).  Stainless steel plate type heat exchangers come standard; shell and tube heat exchangers are available with extra charge.  Water date verification is required.

ENCLOSURE:  Compact unit is soundproofed by a sheet metal enclosure with mineral wool and plastic liners.  Enclosures features a durable powder-coated finish.  Compressor is mounted on base frame with a solid steel floor and vibration isolation mounts.  Additional vibration isolation for airend, motor, and separator tank is standard.  Unit is very maintenance friendly with easy access to all important components through wide opening access door and removable cabinet panels with key locks.

Devices for Ease of Maintenance:  Fluid exchange pressurization valve complete with drain hose; large gasketed and hinged door and removable cabinet panels with key locks and remote grease fittings for fan and drive motors.

Warranty:  Original KAESER SIGMA airend, electric drive motor, and Sigma Control are warranted for a period of two years against defects in materials and workmanship.  The balances of the components are warranted for one year.

Optional Five Year Extended Warranty Program: KAESER will extend warranty coverage for 5 years on the airend, motor and Sigma Control 2 (Parts).  All components not specified in the above description are subject to the terms of KAESERS standard warranty policy.  To qualify for the extended warranty, a customer must purchase one “Annual Warranty Maintenance Kit” at the time of the compressor purchase and one “Annual Warranty Maintenance Kit” each year of the term of the extended warranty.  These new kits include maintenance parts and fluid required for a machine running in a one-shift environment.  Machines running more than one shift will require additional parts and fluid.  Replacement parts and fluid must be genuine KAESER parts.  The kits include micro-fiberglass oil filters, which are a requirement for the Extended Warranty Program.  The fluid included with the kits is S460 Synthetic Lubricant or FG460 Food Grade Lubricant.   After the initial fill is removed from the compressor, the compressor must run S460 or FG460 for the life of the Extended Warranty Program.  We have a free Lubricant Analysis Program as a required part of the Extended Warranty Program.  Recommendations of the Lubricant Analysis Program will supersede the instruction manual. The price of the kit is the same as if the parts are purchased separately. There are no additional charges for the extended warranty kit items.
