Model YCAV Air-Cooled Screw Compressor Liquid Chillers Style A

Accessories and OptionsFORM 201.21-EG1 (711)SOUND REDUCTION OPTIONSOne or all options may be employed by the system designeras normally generated machine noise is consideredin the overall project design:SilentNight - Standard variable speed compressorsresult in a chiller system that has lower part load soundvalues than conventional air-cooled chillers. Over 99%of chiller operating hours occur when building loads areless than design and/or ambient temperatures are lessthan design. As a result, all YCAV model chillers willoperate with less than full load sound output nearly allthe time - this is especially important on evenings andweekends when neighbors are often home. Due to timeof day based sound regulations it may be desirable toforce the chiller to a lower sound level on demand. TheSilentNight control option provides a control input tolimit sound output of the chiller based on time of day.This feature is programmable at the chiller panel or canbe controlled remotely via signal (4-20mA or 0-10 VDC)from a BAS system. (Factory mounted)ULTRA QUIET FANS - With this option, the basic chilleris equipped with specially designed fans and motors toprovide lower sound levels and retain appropriate airflow.The result is reduced fan generated noise with no adverseeffect on the chiller capacity or efficiency performance.(Factory mounted)COMPRESSOR SOUND BLANKETS - Black, highstrength, rip-resistant, two-piece acoustic compressorsound blanket. Material is both UV and mildew protected,waterproof and fire resistant (meeting California fire marshalflame specification). (Factory mounted)Acoustical perimeter enclosures - Galvanized internalbaffles are factory mounted inside of the condensersection. Perimeter enclosure panels that mount aroundthe bottom section of the chiller to reduce sound output.Enclosures panels are painted to match unit panels andinclude sound insulating baffles spaced to allow for properairflow. NOTE: The perimeter enclosures ship separatelyfrom unit. (Field mounted)ELECTRICAL OPTIONSCIRCUIT BREAKER - Power panel will come equippedwith a factory mounted circuit breaker at point of incomingsingle or multi-point connection that provides the following:• A means to disconnect power mounted on chiller.• Circuit breaker sized to provide the motor branchcircuit protection, short circuit protection and groundfault protection for the motor branch-circuit conductors,the motor control apparatus and the motors. (ChillerJOHNSON CONTROLSmounted circuit breaker option sized for branch circuitprotection eliminates the need to provide a separate‘line of sight’ disconnect and separate branch circuitprotection device.)• Lockable operating handle that extends through powerpanel door so that power may be disconnected withoutopening any panel doors.• Short Circuit Withstand Rating of the chiller electricalenclosure when using circuit breaker option is (200V& 230V: 100,000 Amps, 380 & 460V: 65,000 Amps,575V: 42,000 Amps). The enclosure is rated in accordancewith UL508.CONDENSER COIL PROTECTION - Standard condensercoil construction materials include aluminum fins,copper tubes, and galvanized tube supports for generallygood corrosion resistance. However, these materials arenot adequate for all environments. The system designercan take steps to inhibit coil corrosion in harsh applicationsand enhance equipment life by choosing from theseoptions based on project design parameters and relatedenvironmental factors. (Factory mounted)• PRE-COATED FIN CONDENSER COILS - Theair-cooled condenser coils are constructed of epoxycoatedaluminum fins. This can provide corrosionresistance comparable to copper-fin coils in typicalseashore locations. Either these or the post coatedcoils (below) are recommended for units being installedat the seashore or where salt spray may hitthe unit.• POST-COATED EPOXY DIPPED CONDENSERCOILS - The unit is built with dipped-cured epoxycondenser coils. This is another choice for seashoreand other corrosive applications (with the exceptionof strong alkalis, oxidizers and wet bromine, chlorineand fluorine in concentrations greater than 100 gpm).• COPPER FIN CONDENSER COILS - The unit isconstructed with copper tube condenser coils, whichhave copper fins. (This is not recommended for unitsin areas where they may be exposed to acid rain.)PROTECTIVE CHILLER PANELS• WIRE PANELS (FULL UNIT) - UV stabilized blackpolyvinyl chloride coated, heavy gauge, welded wiremesh guards mounted on the exterior of the unit.Protects condenser coil faces and prevents unauthorizedaccess to refrigerant components (compressors,pipes, cooler, etc.), yet provides free air flow. Thiscan cut installation cost by eliminating the need forseparate, expensive fencing. (Factory mounted)• LOUVERED PANELS (CONDENSER COILS ONLY)- Painted steel to match unit panels, louvered panelsare mounted over the exterior condenser coil faces7
