Frequency inverters - Import export

"The demand for speed control has taken off with the advent of IGBTs and powerful microprocessors. Today, there is no longer any difference between DC and AC. 99% of new installations will be equipped with variable speed AC solutions. In our product range, we have both DC and static frequency inverters. Characteristics of a static frequency inverter: OPEN LOOP CONTROL - Single and three-phase power supply between 200 and 480V - Digital inverter - Solution only in 1 or 2Q - Possible braking via chopper and resistor - Power between 0,37kW and 22kW - IP20 protection - Modular drive - We have a stock up to 22kW in single and three phase CLOSED LOOP REGULATION - Single and three-phase power supply between 200 and 500V -Digital dimmer -Solution only in 1 or 2Q -Braking possible via chopper and resistor -Power between 1,3kW and 900kW -IP00/IP20/IP54 protection -Modular drive We have a stock up to 160kW in three-phase 400V"

Scope of delivery Heat Recovery System 90°C including : Specific double cooler 2 nd and 3 rd stage. Special design for 1 st stage intercooler. Internally adapted water circuit. The compressor runs with a smaller water pump with frequency inverter,”VSD”. The compressor runs with a smaller separate water cooling system. External Heat Exchanger Kit for easy connection to the customer system. Features & benefits Features based on L 5 model /200 kW. Temperature : 30-35°C water in – between 85-90°c water out. Power : heat recovered @ 40 bar on load is ca.160 kW = ca.80% of the shaft power. Water : Available quantity of water for Heat Recovery is ca. 2 m³/hour water flow for L5 model. Due to HR a smaller separate cooling system is used for the complete compressor system. One year operation, 6000 running hours @ 0.05 € / kW Heat = 48.000 € savings. Scope of delivery Heat Recovery System 40°C including : External skid Heat Recovery System 40°C with stainless steel plate...

Electrical connections between motor, control cabinet air dryer and water pump. Specific electric motors : protection degrees, IP23 or IP55. Efficiency class : IE1, IE2, IE3. Different optional voltage and frequencies, standard is 400V/3/50HZ or 60HZ +/- 10%. Other voltage is on request : 380V/3/50Hz or 60Hz, 575V/ 60Hz… Soft starter SIEMENS SIKOSTART. Standard is Star Delta starter, the optional soft starter is integrated in the main electrical control cabinet. The compressor is equipped with an electrical pre-lubrication oil pump for the crankcase. Air-conditioning for electrical control cabinet for inside temperatures exceeding 40 for soft starter & 45°C for standard electrical cabinet. The frequency inverter electrical cabinet is protected against high temperature through a different selection of internal components (powerblock…).

This 3-step control switch regulates EC fans, damper actuators, AC fan speed controllers or frequency inverters. It needs 10 VDC supply voltage. The device has an OFF position to stop the motor completely. Thus, the output signal is divided into 4 steps: 0 VDC and 3 other output voltages. The output for position 3 always equals the supplied voltage i.e. 10 VDC. The output ranges for positions 1 and 2 can be adjusted via internal trimmers. There is also a version with 2 predetermined voltage steps: SMT-D-4P-EM

This self-calibrating CO2 sensor measures CO2 as well as temperature, relative humidity and ambient light conditions. It needs a 24 VAC supply voltage. This sensor can also directly control an EC-fan, AC fan speed controller or frequency inverter. It has 1 single analogue / modulating output depending on the highest measured value for temperature, humidity or carbon dioxide. If you only want to use it for measuring CO2, you can deactivate the temperature or humidity measurement. The FCMFX-series are available for different types of supply voltages such as 24 VDC, 24 VAC/VDC or 230 VAC. All version have 3 LEDS on the frontpanel showing whether the measured value is within or out of range. Additionally they are available in a version with audible alert. All parameters are accessible via Modbus RTU. This sensor doesn't need to be configured. Once installed it's ready for use.
