Y's JACKETThis specially designed jacket completely fits Yoshitake products
in use at your site. The energy-saving and CO2-reduction effects
can be estimated prior to order.

Features
1. Energy saving
Prevents room temperature rise as well as energy loss causedby heat release.
2. CO2-reduction effectContributes to CO2-reduction of the global issue.
3. Safety
Prevents accidents, such as burns or bruises and brings a safe
and comfortable work environment.
4. Environmental enhancement
Easy to set and reusable after valve maintenance, it produces
no waste and thus is environment-friendly.
