1 INVERTER ROOF TOP PACKAGE UNITS

2 SMART PACKAGE UNITS Delivering an extensive range, with capacities starting from 11kW up to 270kW, incorporating inverter technology throughout our roof top package units. Providing a genuine solution for a variety of projects, whereby our air-cooled SMART package units can be more economical and efficient than a chiller plant for a similar type of commercial installation. This is achieved from the use of a inverter capacity scroll compressor, electronically controlled fans, free-cooling and reduced installation time. This means a SMARTPAC solution can form an integral part of a medium to long term sustainable energy strategy and help stores reduce their carbon footprints. Technology and efficiency from tomorrow delivered today, an evolution in design and custom engineered solutions for small, medium and large sized air conditioning applications. are dedicated to providing market leading innovations and new technologies that are easy-to-use solutions with the goal to always offer our client reduced energy outlay whilst empowering complete control to customize the solution for their business. SHOPPING CENTRES, TENANCY FITOUTS, UNIVERSITY AND OFFICE BUILDINGS. High efficiency INVERTER scroll compressor technology combined with electronically controlled (EC) supply and condenser fans. A smart package unit capable of managing the strategy to deliver the most efficient cooling method on the market via, inverter compressor, vairiable supply and condenser air, fresh air management and free cooling. PacAir RTU s are designed to operate from C to 50.0 C ambient conditions, they are manufactured from double skin panels, ensuring thermal protection and longevity of equipment. Meetings MEPS regulations, AS3666 and AS3000 and incorportate an economizer as standard throughout the entire range will ensure customer satisfaction. The high level interface (HLI) controller will monitor space conditions and control air quality through an integrated CO2 probe, ambient conditions, humidity, free-cooling and complete variable capacity control, providing precise comfort and a reduced energy footprint. Incorporating intelligent control technology with market leading inverter and EC components throughout the SMARTPAC range.

3 COMPRESSOR(S) Maximum electrical power is only required for certain periods of operation, maximum efficiency when operating at part load operation is essential. Continuous modulating control is obtained by using a compressor with inverter technolgy, which adapts to the actual requirements of the building load and space served. DISPLAY User friendly wall mounted touch screen display pad, easy to understand menu, adjustable temperature set-point and display of current space temperature and humidity through its built-in sensors, 365/weekly/daily programming with after-hours control and fault status. ELECTRONIC EXPANSION VALVE Optimum control of superheat at varying operating conditions, providing outstanding comfort with indoor air temperature and humidity control. EXV increased efficiencies by lowering head pressure and optimum refregrant supply to the heat exchanger coils. FAN(S) The selection of electronically controlled (EC) brushless motors reduces acoustics, heat and wasted energy. Allowing the EC fans to adjust speed by means of the condensing pressure or supply air temperature. Modulating the speed based on the actual requirements, maximizing the energy efficiency of the cooling circuit and simultaneously reducing the electrical load. The decreased air volume also has a significant effect on the reduced acoustic levels. With seasonal and night time functions continuially controlled by the intelligent controller, allowing the unit to operate when maximum cooling or heating capacity is not required savings power and reducing operating costs. HIGH LEVEL INTERFACE CONTROLS PacAir RTU SMART controller can easily be integrated into Building Management Systems (BMS) that use BacNET IP as a communication protocol. Monitoring the SMARTPAC at high level, communcating to adjust set points, airflows, operating times, after hours and monitor any faults, alarms and the filter status. The serial connection port is built-in to the electronic board and is a standard feature throughout the range. SMARTPAC is also equipped with an IQ controller for the automatic control of all operating conditions, ambient temperature, humidity, CO2 and incorporates functions to maintain space coditions and optimize the running-cost of the PacAir RTU all year round. With advanced maintenaince and service functions scheduled, this Package Unit is setting a new level of expectations in the market. FREE-COOLING As external ambient conditions change, the opportunity to provide free-cooling is incorporated into our high level inface controller. The unit is capable of automatically activating the free-cooling mode when conditions meet the controls internal alogrithum and space conditions. Keeping the compressors off and drawing in suitably filtered fresh air allows to cool the space. This operating mode is especially useful during cooler periods and night time operation when high ambient conditions are reduced. It allows substantial reduction of the unit energy consumption. R410A COIL TREATMENT Condenser coils are treated as standard with Aeris Coil Treatment. The evaporator coil can be treated as required and is an option based on the project requirements. REFRIGERANT ECO friendly R410a refrigerant pre-charged units. FILTERS AND PLENUM Basic G4 pre-filter and F7 high filteration as standard. Optional F5/F6/F7 50 or 100mm panel filters available or H10 electronic filter systems.

4 REDUCED OPERATING COSTS AND ACOUSTICS The SMARTPAC s controller, cooling circuit, EC fans and high capacity filter sections allows your building to breathe fresh to the most efficienct operating costs on the market. It is possible to achieve seasonal effciencies by selecting and purchasing the best the market has to offer. Reduced electrical consumption up to 60% in comparison to traditional DOL solutions. As a result, this also reduces operating costs and the environmental impact of the system, achieved by reducing the amount of energy required for normal operation. The reduction in wear and tear by brushless fans not only improves energy but also reduces the acoustic levels and improves enviromental standards. d B ( A ) R A D I A L F A N S U P T O 11 d B ( A ) R E D U C T I O N E C I N V E R T E R P L U G - F A N S EASY MAINTENANCE Plug-and-play style Package Unit with the power and control wiring is easy to connect to the rooftop unit. Small compact footprint, easy access to all components and easy replacement solution for old units. Reduced maintenance costs with dirty or fouled-filter detection through the controller interfacing with the BMS. Commissioning, service and maintenance contracts, as the Pacific HVAC Service Division is at your disposal. F A N S C O M P R E S S O R M A X LIFE CYCLE INCREASED The external rotor electric motor is driven by the continuous magnetic switching of the stator. The advantages are The lack of brushes and the particular power supply increase effciency by 70%; Even the life cycle increases, thanks to the elimination of the brushes natural abrasive erosion e_ects; The electronic control also includes a soft start solution, which drastically reduces the starting current of the fan and limits even more the system s electrical commitment.
