PW - Power, voltage, frequency selection
Although the standard oven is designed for 480 volt / 3phase service and 24-volt control power, we can design it to accommodate any international voltage and frequency requirement.
Please select one of the options below, or if your specific power requirement is not shown, select PW4 and explain your exact power requirements.
- PW1 480 volt / 3 phase / 60hz primary power and 24vdc control power.
- PW2 380 volt / 3 phase / 50hz primary power and 24vdc control power.
- PW3 400 volt / 3 phase / 50hz primary power and 24vdc control power.
- PW4 415 volt / 3 phase / 50hz primary power and 24vdc control power.
- PW5 575 volt / 3 phase / 60hz primary power and 24vdc control power.
- PW6 Custom power - please describe.
If you are unsure about your exact requirements, please see the following document for international voltage and frequencies. Note: ASC's manufacturing plant is in the US and therefore utilizes 480V/3PH power. For this reason, when PW2-PW6 is selected, ASC will be required utilize rental diesel generator power to test the oven during in-house tests. This generator rental cost as well as a slight increase in motor costs will be priced into the project, so one should expect a slight increase in autoclave price when PW2-PW6 is selected.
VP - Vacuum pumps
While some customers prefer to use in-house vacuum systems to supply vacuum to the oven, most prefer that a dedicated pump or pumps be provided on the oven.
- VP1 One vacuum pump, fully integrated to autoclave, with PC controls.
- VP2 Two vacuum pumps, fully integrated to autoclave, with PC auto-switching and redundancy logic/controls.
ASC standardizes on an Airtech L-series, rotary-vane, oil-seal vacuum pump for our aerospace vacuum applications. The Airtech pump includes an exhaust filter, vibration isolators, and anti-suckback valve. The pump achieves a vacuum level of 29.8 "Hg (2 mmhg) at 60hz operation and sea-level.
For the VP2 option, ASC will provide two (2) pumps with PC-control logic that allows manual selection of a single pump, dual pump operation, auto-switching for balance duty and redundancy.
Pump Ratings
For composite applications, ASC has developed a simple rule of thumb for sizing vacuum pumps. We generally offer a pump that delivers a capacity that will provide approximately 2 cfm to each of the autoclave's source lines. For example, a 10 source line application, we would select an L25 pump, which delivers 20 cfm.

VT - VacTrap ™ chilled resin traps
For composite curing applications with high volatile content (ie. high-temperature polyimides), we recommend chilled VacTrap ™ assemblies instead of the conventional ambient temperature filter traps. The VacTrap will be much more effective in condensing volatiles and solvents during high-temperature curing operations.
The VacTrap is an ASC designed modular vacuum system that utilizes conventional stainless-steel ball valves, a proprietary custom aluminum trap blocks, and a chiller.
VR - Controlled vacuum receiver system
Many composite applications require full vacuum during and or at the beginning of the cure cycle. In these cases, there is little need to control the level of the vacuum to the parts. However, for high-temperature polyimides and honeycomb reinforced parts, there is often the need to provide partial vacuum (ie. -10"Hg) to the parts. In these cases, you will need to have a controlled vacuum receiver.
The VR option provides an integrated receiver tank, transducer connected to PC system, and two PC-controlled valves. Once configured, the system will provide Recipe-based programming and control of the system vacuum to +/- 1" hg (24 mm Hg) accuracy. The VR option includes solenoid operating valves for ovens with minimal vacuum source ports, and proportional valves for larger oven systems.
