Miembero SECON
SECON was founded in 2010 with the objective of manufacturing liquid chillers exclusively on the basis of natural refrigerants and now is one of the pioneers in the use of hydrocarbons (in particular R290, R1270 and R600a). SECON is considered the market leader in this market segment in German-speaking countries. Thanks to the project-specific design of all units and the flexible customisation options, Secon is always the first choice when it comes to quality and efficiency. In addition, all Secon machines have a comprehensive and proven safety concept, which ensures the safe use of flammable refrigerants. …
Buenas prácticas Product: FXP compact chillers
The FXP series comprises 3 power sizes of extremely compact water-cooled chillers, which are intended for modular arrangement. The modules are particularly suitable for retrofit applications, when the installation allows only very limited unit dimensions. The individual modules have a cooling capacity of up to 45 kW and cover outlet temperatures from +20 to -15°C. As a rule, several modules are always installed in a hydraulic network. This results in excellent reliability and very good controllability of partial loads. If desired, the individual modules can be controlled separately or via a central control system. …
Buenas prácticas Product: KRONOS water-cooled chillers
The KRONOS series from Secon is specially designed for water-cooled applications and also uses the natural and highly efficient refrigerant propane (R290). All units have their own enclosure with gas monitoring and ATEX hazardous area ventilation and can be installed in suitable machinery rooms. Alternatively, the units are also available with a weatherproof housing for outdoor installation. The series covers cooling capacities from 60 to 700 kW and can be used in a wide temperature range with outlet temperatures from +20 to -35°C. LT models use propylene (R1270), which is also a natural refrigerant. The units can be equipped with 1 to 4 reciprocating compressors. The capacity control is either stepped or stepless with inverters. The units already have a special, highly developed control system as standard. Optionally, they can also be equipped with a Siemens S7 industrial control system. …
Buenas prácticas Product: STRATOS air-cooled chillers
The STRATOS series from Secon is the flagship among the air-cooled propane chillers. The series covers cooling capacities from 150 to 1,200 kW and can be used in a wide temperature range with discharge temperatures from +20 to -30°C. As standard, the units can be operated at ambient temperatures from -20 to +40°C (tropical version available on request). LT models use propylene (R1270), which is also a natural refrigerant. The units can be equipped with 1 to 4 reciprocating pistons or 1 to 2 screw compressors. The capacity control is either stepped or stepless with inverters. The units already have a special, highly developed control system as standard. Optionally, they can also be equipped with a Siemens S7 industrial control system. All units are designed specifically for the project and can be equipped with various options (pumps and/or hydraulic modules, heat recovery or free cooling). …
Buenas prácticas Prototype and Test
When you have a new idea or want to improve system performance, first use simulation to evaluate if the idea will work. When design results are promising, take the concept to the lab for initial prototyping and testing. Such work can help inform proper component selection, controls settings, and system integration considerations. …
Buenas prácticas Design Optimization
Many times we find that products are designed to meet quick timelines, rushing to achieve the best performance possible in as short an engineering cycle as can be obtained. This often leads to a "trial and error" approach. Mathematically rigorous optimization can find a LOT of room for improvement - and doesn't have to be time consuming or delay product development cycles. Leveraging the right approach and software can make a big difference in achieving greater product performance. …
Miembero Optimized Thermal Systems, Inc.
Optimized Thermal Systems was founded in 2002, with the goal to provide crucial heat transfer and system integration expertise to the industry specifically in the areas of air-conditioning, heat pumping, refrigeration and energy conversion. Having roots with faculty and research at the University of Maryland, our main office in Beltsville, MD includes comprehensive laboratory facilities. Our goal is to be your reliable, experienced partner in heat transfer, product innovation and system integration. We do this by offering expert services in consulting, software development, workshops, experimental testing & validation, and prototype development.

Buenas prácticas Policymaking: The Australian Refrigeration Association stirs up the Federal Department of the Environment
The Australian Refrigeration Association (ARA) is preparing its third submission to the Federal Department of the Environment regarding the Review of the Ozone Protection and Synthetic Greenhouse Gases Management Act (OPSGG MA). In its previous 2 submissions, ARA was supported by over 70 of the leading cooling and refrigeration organizations. Now ARA is calling upon the public to show its support for the third submission. The submissions focuses on the reduced use of hydrofluorocarbon (HFC) refrigerants. ARA estimates that the transition to natural refrigerants may reduce the cost of HVACR services in Australia by up to $10 B per annum, and reduce national GHG emissions by 7%. ARA is encouraging individuals to write a unique response about why they believe the Federal Department of Environment should prioritize this thematic. The key recommendations include: Banning the use of HFC’s in new vapour compression systems with a charge >5 kg by 2025. Compulsory use of low GWP refrigerants in all new vapour compression systems with a charge <0.150 kg by 2025. The introduction of a series of mechanisms to deliver minimum energy efficiency benchmarking, skills based refrigeration licensing (as opposed to refrigerant based licensing), alignment of WH&S legislation making state and federal WH&S legislation nationally consistent. …
