4 Compact CWE STULZ Compact CWE floor mounted /C s are designed to be the compact solution to your precision air conditioning requirements. Systems are available in sizes from 10 to 100 tons in a variety of space saving cabinet foot prints. Efficiently designed for 100% front service access, STULZ Compact CWE units can easily be tucked into a corner, between cabinetry or side-by-side. STULZ Compact CWE units are especially adaptable to raised floors and are available in both down-flow and upflow air pattern configuration. Compact CWE Systems Offer Outstanding dvantages Versatility Microprocessor Control Down-Flow and Up-Flow ir Patterns Ducted Systems Raised Floor Mounting with Floor Stands Optional Under Floor Fan Mounting Precision temperature and/or humidity control with highly versatile and flexible E 2 series controls. Designed primarily for STULZ precision air conditioners, E 2 controllers offer a wide range of expanded control functions and alarms. Outstanding dvantages 100% Front Service ccess From tons, STULZ Compact CWE systems are designed for 100% Front Only ccess. The compact foot-prints require minimal floor space and are easily tucked into a corner, between cabinetry or side-by-side. Non-Proprietary Parts STULZ Compact CWE systems incorporate non-proprietary components where possible. Most major HVC, refrigeration and electrical distributors stock an exact model cross reference or an alternate to most factory provided components. Code (UL / CS) Conformance The E 2 controller features a menu-driven operating environment to allow system setup and operation via an easy to read user interface display panel which is typically mounted on the front door of the STULZ Compact CWE system. Electronically Commutated (EC) Fan Maintenance free, highly reliable EC (Electronically Commutated) Fans offer considerable cost savings and long life. Fan speed is continuously adjustable via a signal from the system controller without the use of VFD s. EC fans offer energy efficient, quiet and low vibration operation.
