Coated Air CoilsAll Evaporator coils are baked enamel coated with a corrosion resistant material. This coating protects against most airbornechemicals that can lead to accelerated corrosion and premature failure of the coil. All coatings are factory applied for total coil coverage and must pass the equivalent of an 1000-hour salt spray test. Baked coating provides superior protection against corrosion due to acids, solvents and salt found in a typical environment and which could lead to premature failure of the coil. Application of baked coating has a negligible effect on the coil performance.

Four Sided Filter RackBosch’s units include either a 1" or 2" air filter. Four sided filter racks minimize unfiltered air from entering the unit. Filter doors allow for easy routine maintenance and changing of the air filter. MERV 11 high efficiency filters are available on most units.

Stainless Steel Drain PanAll Bosch units utilize stainless steel drain pans. A stainless steel drain pan prevents corrosion and allows for easier cleaning. It will not deteriorate over the life of the unit.

Filter DrierA filter drier absorbs moisture that may be contained within the refrigerant system. Moisture is detrimental and can possibly damage the compressor when it mixes with the refrigerant.

Floating Base PanThe floating base pan isolates the compressor from the cabinet and absorbs the vibration energy so that it does not get transmitted to the space. Even under normal operating conditions vibration may be transmitted to the building and introduced into the space as noise. This feature, unique to Bosch is standard in all of our units to ensure quiet operation.

TXV ValveHigh quality thermal expansion valves (TXV) allows for greater flexibility in operation over a wider range of conditions allowing them to closely match the demand of the unit and run at optimal efficiency. The TXV is installed in the compressor section for easy access and servicing.ensure quiet operation.

R410-A RefrigerantBosch’s entire product line features the environmentally friendly R-410A refrigerant. R-410A is a non-ozone depleting refrigerant since it does not contain any chlorine. R-410A is classified as an HFC (Hydrofluorocarbon) refrigerant as it only contains Hydrogen, Fluorine and Carbon. This refrigerant is the industry’s replacement for refrigerant R-22.

Coaxial Heat Exchanger CopperOversized coaxial refrigerant to water heat exchangers are standard in all units. The customer can choose between Cupronickel or Copper coils. These coils are designed to allow optimal heat transfer while offering extremely low pressure drop. This unique low pressure flow design reduces the amount of pumping power necessary to achieve optimum water flow in order to maintain the efficiency of the unit. Coaxial heat exchangers are not as susceptible to clogging and freezing as are plate heat exchangers. All geothermal units come standard with a wrapped insulated coaxial heat exchanger. The insulation wrap prevents condensation from forming in low temperature operations.

GeothermalThis unit comes ready for geothermal application.

Scroll Compressor 2 StageThe performance of regular scroll compressors is taken to the next level with these two stage units. A simple solenoid valve bypasses refrigerant providing two stages of operation. This feature translates into the most efficient unit performance on the market today, ensuring you peak performance and energy savings under widely differing operating conditions.

Compressor BlanketA high density compressor blanket together with the unique floating base pan can reduce sound levels by up to 60%.

Motor Control InterfaceTo obtain the optimum performance from your Bosch unit the Motor Control Interface board was designed to translate inputs from the thermostat to the unit. The start/stop ramp up/down and the speed of the blower under different operating conditions are determined by the settings MCI board which may be customized to meet specific job site conditions.

Unit Protection Module 1The Unit Protection Module UPM1 is standard on most single compressor Bosch units and was developed to enhance their operation.The (optional) freeze protection will prevent unit operation below either 35° F (1.7° C) or 15° F (-9.4° C) leaving fluid temperature depending on the dip switch setting. The condensate overflow option prevents unit operation in the event the drain pan clogs and there is a potential for condensate overflow. Each controller has a random start feature programmed into its microprocessor ranging from 270 – 300 seconds preventing the simultaneous starting of multiple units. An anti-short cycle timer allows a 5 minute delay on break timer to prevent compressor short cycling. A low pressure bypass timer switch prevents nuisance lockouts during cold start up. The high pressure switch delay of one (1) second provides switch stabilization on start up to prevent

nuisance lockouts.

The Unit Protection Modules monitor the operating condition of the unit by providing:

A Brownout / Surge / Power Interruption

Protection against high or low pressure conditions preventing potential compressor damage.

Malfunction Output - The controller has a set of contacts for remote fault indication. These may be set for either a pulsed or constant output as well as providing either a 24 volt or dry contact closure.

Test / Service option - A dip switch is provided to reduce all time delay settings to 6 seconds during troubleshooting or operation verification.

L.E.D. Indicators for fault identification and power.

Intelligent Reset. Two or four attempts to restart before going into a hard lockout requiring manual reset. Dip switch adjustable.

ECM Blower Motor These units offer as standard a variable speed GE 2.3 ECM blower

motor. This highly efficient programmable motor will maintain constant

airflow in the air distribution system despite changes such as the air

filter loading. Air delivery is matched to the stages of operation to

maintain comfort conditions and maximum savings under a wide range

of operating conditions.

2" MERV 11 FilterMERV 11 filters provide enhanced removal of dust and pollutants from

the air stream maintaining a healthier environment in your home.

Coaxial Heat Exchanger CupronickelIn ground water geothermal applications, the Cupronickel option provides additional corrosion protection in situations where the water may contain a higher level of chemicals.

Hot Gas ReheatThe Hot Gas Reheat (HGR) option allows the user to not only control space temperature, but also space humidity levels. An excess of moisture in the space can allow mold growth, leading to damage to the structure or interior surfaces, as well as reducing the air quality and creating an unhealthy environment. A unit is normally controlled only by a thermostat. The thermostat may be satisfied at 70º F, however, the humidity may be at an unacceptability high level. Based on temperature alone, the unit will not run because the thermostat has reached the set point. In order to reduce the humidity levels, the heat pump must continue to operate in the cooling mode to remove humidity from the air. This may result in producing colder air than desired, leading to uncomfortable space temperatures. By utilizing a humidistat the unit is able to monitor the humidity levels in the space. The HGR option allows cooling and dehumidification to satisfy both the thermostat and humidistat. Once the thermostat reaches set point and the humidity is above set point the unit will cool and dehumidify the air, then be reheated by hot refrigerant gas and delivered to the space at around room temperature. The unit is operating as a dehumidifier. This option offers significant energy savings over the traditional means of reheating air with electric heating coils.

Desuperheater*A desuperheater or HRP (Hot Water Heat Recovery Package) is a feature that takes advantage of waste heat of the compressor and uses it to heat domestic water. Heating your water with FREE waste heat will reduce the use of your inefficient water storage tank heating elements. Hot water is produced by using a double wall coaxial heat exchanger coil. The hot refrigerant gas flows in the outer tubing while the domestic water flows in the inner pipe being heated by the hot refrigerant. The HRP heats water with superheated gas that is being produced by the compressor as you heat or cool your space, thus saving you money in your hot water production.

Comfort Alert Diagnostic ModuleThe Alert Diagnostics module is installed in the electrical box of our units. The tool monitors data from the thermostat and compressor and records any malfunction of the system. LED lights provide the alert code and lead the service technician to the cause of the malfunction. The Alert Diagnostics module can significantly reduce maintenance by improving system diagnostics by up to 75% over systems without this feature.

Electric HeatElectrical heaters are available from 5 through to 20 kW. Ask your Bosch dealer about which sizes and combinations are available for your unit.
