How to choose the right SmartTronic model

30–37 kW (ST 30+ / 37 / 37+) → medium-sized industrial companies with 30–60 employees, automotive subcontractors, plastics plants with 3–5 injection molding machines.

45–55 kW (ST 45 / 45+ / 55 / 55 Vario+) → large production plants, paint shops, forges. Plus (+) versions provide 10–15% higher delivery with the same motor.

75–110 kW (ST 75 / 90 / 110 + Vario) → the largest industrial companies, automotive plants (Škoda, Hyundai), power plants, cement plants, steelworks.

Vario version → operations with irregular or variable consumption. The Danfoss VLT inverter saves 20–30% energy. Payback is typically 2–3 years.

FD version (Fusion dryer) → if you need dry air (dew point +5 to −20 °C). Integrated solution — no separate dryer. Saves energy and space. Standard equipment includes a filter + cyclone separator.

Key SmartTronic technologies

★ Premium technology

A150 screw airend — 5th generation

For the overall energy efficiency of the compressor station, one of the key components is the proprietary A150 screw airend, which was developed in cooperation with the Department of Screw Compressors at City University London.

It features a special 5th generation N-profile rotor teeth. The latest screw compressor technology brings, so far, the best energy efficiency of a screw airend on the market.

3D dimensional inspection to within thousandths of a millimetre
Very high energy efficiency on the market
High resistance to vibration
Exceptional service life and reliability

Innovative solution

FD fusion dryer — revolutionary drying system

The most economical drying method capable of achieving negative pressure dew point values. The dryer is integrated into the compressor, equipped with compressed air filtration, and uses waste heat and waste process air for its operation.

Operation is fully automated and controlled based on humidity measured at the compressor outlet. The required pressure dew point can be set in the range of +5 °C to −20 °C on the compressor controller.

Adsorption principle with two columns (working + regeneration)
Use of waste compression heat for regeneration
Reduction of energy consumption for drying by ~50 %
Integration into the housing — no separate dryer

Standard in FD

Compressed air filtration

In machines with fusion drying, a compressed air filter and cyclone separator are installed as standard. For other machines, they can be offered as an option.

Filtration ensures high air quality at the outlet for the most demanding industrial applications — food industry, medical technology, fine pneumatics.

Cyclone separator — separation of moisture and oil
Compressed air filter — purity class according to ISO 8573
MANN+HUMMEL filter cartridges

Advanced control

LOGIK 26-S — new advanced controller

The LOGIK control unit controls the operation of the compressor and monitors all main functions. In addition to basic parameters such as pressures, temperatures, and operating states, detailed operating data are also monitored.

Monitoring — operating hours, time under load, % load, number of starts/h
Logs — fault log, maintenance log, ATMOS Care
Remote communication — MODBUS/RTU
Scheduling — up to 3 daily schedules for each day of the week
Master-Slave — mode for controlling two compressors
Multilingual menu + remote control

Vario models

Danfoss VLT inverter

The Vario model range is equipped with Danfoss VLT inverters. Smooth regulation of the screw block speed according to current compressed air consumption.

Together with the modulating valve (which, as an option, enables proportional control via the intake valve), this results in energy savings and reduced load on the machine. Typical energy savings of 20–30% in operations with variable consumption.

Accessories — options

ARCHON — master control system

Built on the platform of the highly reliable industrial solution SIEMENS Simatic S7-1200. Used to control 3, 5 or 9 compressors over a digital line.

Up to 10 weekly schedules — different modes for weekdays / weekends / holidays
3 control methods: fixed priorities / operating hours / highest efficiency
Up to 3 independent pressure schedules for different pressure levels
Communication via Profinet or Modbus
Optionally a wide range of customer solutions

Frequently asked questions

What is the difference between ST 30, ST 30+ and ST 30 Vario+?: The ST 30+ is a higher-performance version (higher delivery at the same 30 kW motor). The ST 30 Vario+ adds a Danfoss VLT inverter — stepless capacity control, 20–30% energy savings with variable consumption. The ST 30 (without +) is not in the current price list.
What does FD mean in the ST xx + FD version?: FD = Fusion Dryer integrated directly into the compressor casing. An adsorption dryer utilizing waste compression heat for regeneration. Achievable pressure dew point +5 °C to -20 °C (down to -40 °C with additional equipment). Energy savings compared to a standalone dryer.
What is the difference between the A150 block and SCA-14/SCA-20?: The A150 is a 5th generation ATMOS block with an N-profile rotor (London City University) — used in the ST 30-55 kW. SCA-14-G-R and SCA-20-G-R are blocks for higher outputs of 75-110 kW (larger rotors, higher delivery). All three blocks are oil-lubricated with high efficiency.
Can I choose a working pressure other than 7.5 bar?: Yes. SmartTronic is available in 4 pressure variants: 7.5 / 8.5 / 10 / 13 bar (selected during manufacturing). At higher pressure, delivery in m³/min decreases. For higher pressures of 14-25 bar, an inquiry is required — ATMOS also supplies special variants.
How does the ATMOS Plus remote management work?: ATMOS Plus is a cloud application for remote monitoring of compressors. Using a communication unit, the compressor is connected to the internet (Profinet / Modbus). You monitor pressure, operating hours, temperatures, and service intervals. Remote setting of pressures and alarms is possible. Included free of charge with SmartTronic.
What is 72% heat recovery and how is it suitable for production?: The compressor produces heat (94% of the input electrical energy) when compressing air. The ATMOS heat recovery exchanger captures this heat from the oil circuit and transfers it to the water circuit (heating, domestic hot water). Up to 72% of the input electrical energy can be reused. Return on investment typically within 1 year.
What is ARCHON and when is it suitable?: ARCHON is a superior control system based on Siemens Simatic S7-1200 for coordinating 3, 5 or 9 compressors as 1 source. Up to 10 weekly schedules, 3 control methods (priority / engine hours / highest efficiency). Profinet / Modbus communication. Suitable for central compressor stations with multiple machines.
