Vacuum Defoamer SIE‑ZK500
Balanced Capacity & Multi‑Segment Temperature Control · Handle Medium‑Batch Mixed Materials With One Unit
125L balanced capacity for multi‑material parallel processing + Uniform three‑sided thermal radiation heating + Unattended automatic constant‑pressure cycle
SIENOX SIE‑ZK500 vacuum defoamer adopts 125L chamber of 500×500×500 mm. Three‑sided thermal‑radiation heating keeps temperature deviation within ±5℃. Automatic constant‑pressure cycle stops pump upon target vacuum and restarts when pressure drops below threshold. Multi‑segment temperature control ranges from ambient to 300℃. Non‑contact vacuum defoaming retains material original chemical properties.
✓ ISO9001 Quality System ✓ RoHS Compliance ✓ Customizable voltage (110V/220V)
Why Must Microbubbles in Materials Be Eliminated?
Residual micro‑bubbles degrade end‑product quality directly
LED Lighting IndustryBubbles inside LED strip potting compound cause uneven light transmission and reduced luminous efficiency. In medium‑batch production, inconsistent defoaming results across positions trigger yield fluctuation. Three‑sided uniform thermal‑radiation heating ensures even chamber temperature. 125L volume fits medium‑batch LED potting defoaming and guarantees consistent defoaming performance per batch. | Plastic Toy IndustryBubbles in potting compound and coating materials raise defect rates for mass‑produced plastic toys. Frequent temperature adjustments are required for medium‑batch multi‑variant change‑overs. The balanced‑capacity 125L chamber with dual mesh plates enables simultaneous multi‑material processing without batch separation. Three‑sided heating delivers uniform defoaming effect for parts at different positions and lowers intra‑batch quality fluctuation. | Silicone Rubber IndustryBubbles in liquid silicone lead to surface defects after vulcanization and sealing failure of gaskets. High‑viscosity silicone de‑foams slowly at room temperature. Vacuum‑assisted heating cuts viscosity to speed bubble escape. Three‑sided thermal‑radiation heating maintains uniform temperature throughout the 125L large chamber for stable, repeatable silicone defoaming results. |
✨ Dilemmas of conventional solutions: Multi‑variant products require diverse temperature parameters. Ordinary equipment suffers poor temperature accuracy and uneven chamber temperature. Long commissioning time for product change‑overs hurts throughput. Manual vacuum monitoring brings high labor cost with human‑error risks. Poor vacuum‑holding performance for high‑volume processing triggers frequent vacuum‑pump cycling and shortens service life.
Why Choose SIE‑ZK500
Solve temperature‑control & efficiency pain points for medium‑batch multi‑variant production
Three‑Sided Uniform Thermal‑Radiation HeatingSimultaneous heating from left, right and bottom of inner chamber. Thermal radiation delivers even temperature distribution with deviation within ±5℃. Consistent defoaming performance for products at all positions, avoiding overheating near heaters and insufficient defoaming far from heat sources. PID+SSR control achieves ±0.5℃ precision for fast, stable temperature switching between multiple materials. | Automatic Constant‑Pressure CycleVacuum pump auto‑stops at set vacuum level and restarts when pressure drops below threshold to maintain steady chamber pressure. No manual vacuum monitoring required to cut labor cost. Pressure‑holding leakage rate approx.1.0KPa/hour. Low pump‑cycling frequency reduces noise and extends pump service life for long‑hour continuous operation. | 125L Balanced Capacity500×500×500 mm chamber equipped with 2 mesh plates. Medium‑size chamber suits medium‑batch multi‑variant production. Handles decent volume per batch without slow vacuum pumping or high energy consumption caused by oversized chamber. Capacity nearly doubles versus ZK400 for small‑batch runs. One unit covers core production requirements. |
✨ If you produce multi‑variant products, require precise temperature control or unattended continuous operation, ZK500’s three‑sided heating and auto constant‑pressure effectively reduce manual intervention.
Working Principle
Bubbles expand and burst under negative pressure for gas escape to improve material compactness.
Step 1: Vacuum pumping to build negative pressure: The built-in vacuum pump reaches -100kPa within 3-5 minutes. The negative pressure environment expands bubbles inside materials. Step 2: Heating-assisted defoaming: Thermal radiation heating adjustable from room temperature to 300°C reduces material viscosity and accelerates bubble rupture and escape. Step 3: Non-contact purity preservation: Materials stay static inside the vacuum chamber with no contact from stirring paddles, keeping the chemical properties of materials unchanged. Simple three steps: Vacuum Pumping → Heating Assistance → Non-contact Purity Preservation to improve material compactness. |  |

What is the function of a defoaming machine?
A defoaming machine is a device used to remove bubbles from liquids. Its function is to assist in the liquid mixing, reaction, coating, printing, infusion and other process steps in the production process, avoiding the generation of bubbles and their impact on the final product. In many industrial and laboratory environments, removing bubbles is essential as they may have a negative impact on product quality, such as affecting surface tension and stability. Defoaming machines typically use various techniques such as vibration, ultrasound, centrifugation, etc. to achieve effective bubble removal. It has a wide range of applications, including but not limited to semiconductors, solar energy, optics, biotechnology, materials science, etc.
