2. Description of accessories
a. Steps or stepless capacity control system
Please refer to chapter 2.6 and 2.7 for the detail of step or stepless capacity control system.
b. Compatible steps and stepless capacity control system
For customers’ ease of stock control, possible modification of capacitycontrol logic in the future, or other special
requirements of capacity control, Hanbell deliberately designs devices for stepless/step dual capacity control as
nonstandard accessory for customers’ choices. Logic of stepless/step dual capacity control is basically identical to
those of stepless or step capacity control respectively. Please refer to Chapter 2.6, 2.7, & 2.8 for further details.
c. Suction and discharge check valve
Hanbell standard check valve (vertical type) is gravitydriven with characteristics of large flow volume and low
pressure differential. After shutdown of compressor, Teflon taper guider inside can simultaneously seal up the
precisely machined base of check valve by gravity force to effectively prevent return of highpressured gas to
compressor. The gravitydriven check valve is equipped vertically. Due to limitation of space or piping requirements,
alternative horizontal check valve is also available.
